[rangersct]

Im sure she is nice but i hope she teaches better than that...no explanations at all. People are commenting to answer questions that should have been explained to begin with.

[Allie8Ms]

MAN...i get A's on my papers because of her.

[skullker25]

its 20 because its the greatest common factor.=)

[booark]

thumbs up if you agree to nothing :D

[Canada2210]

Thumbs up if you agree at my below comment :P

[Canada2210]

You use 20 because it fits into both 100 and 40! You should know this!!!!!!!!!! -.-

[reservoirdog42]

jeez, so serious

[crystalglamz2k11]

That dont even make sense! soz but you're not a great teacher you should explain why you have to divide by 20 but no. Instead u just decided to go and carry on writing. Thanks tho anyway :)

[NinjaDinosaur321]

@crystalglamz2k11 Because 20 is the greatest common factor.

[Miyukimeyon]

Finally a teacher who wont scold me when im not listenng....

[fjordtru]

I've jsut noticed that youtube is now a LOT better than before. Don't u guys like the design?

[kimy119206]

@fjordtru no not relly aww that sucks man i wish i could change it back..:((

[runnergold]

why do you have to divide by 20?

[kimy119206]

@runnergold becuz it the highest number that fit's into both numbers wich are 40 and 100.it's the highest nuber u can syplify it with.:P

[robbysharolaid]

@runnergold Because it's the lowest or highest (I can't remember) number that both 40 and 100 can go into. :)

[Son0fHobs]

[th3bl3ss3d]

omg this was exactly the problem in meh pre algebra homework lmfao 40% turn to fraction lolz

[wwefan987654]

Wow, Her accent is SO strong. :S

I'm british okay. :P Gimme a break. xP

[VictoriaAndDesi]

She divided by 20 becuase you need to simplifythe fraction, 20 is the greatest common factor, so divide by 20 for this problem,. thats how she got it

[FlashWhiteSnoW]

She used 20 because it's a common number between 40 and 100

[lee001ful]

last year i barely touched my textbook and here i am watching a video about man on youtube when i could be like jammin' out to my hommies! Well, I feel like a completly diif person! O_o

[Euclides287]

I fucking hate Justin Bieber!! >=( Ups! Wrong classroom, sorry to disturb you guys. <=s

[minecraftdude11]

♥♥♥♥♥♥♥♥♥ haahhahaha♥♥♥♥♥♥♥♥♥♥ y is she not hot♥♥♥♥

[minecraftdude11]

y did she use 20?

[VintagePoise54]

@minecraftdude11 EXACTLY lol why did she use 20? i need help hereee

[dollface188]

She Makes iT So EASY!! iLoveeiT!! lol. . . Unlike My Math Teacher iAsk Her A Question And She Starts Drawinq Arrows &'Box's-___-

[TheHotepsekhemwy]

40/100 why do we have to divide by 20?

[MuspellianMagickian]

@TheHotepsekhemwy

to reduce the fraction into lowest terms...you don't HAVE to but it just makes the fraction easier to grasp.

[allyfv]

@TheHotepsekhemwy exactly what i am thinking

[moodypanda130]

@TheHotepsekhemwy you have to divide by 20 because that will make the answer in lowest terms. Because if you divided by 2,4, or 10 it could still be reduced more... thats why she did 20 because it is the Greatest Commom Factor of both numbers... I hope this helped! =]

[zoelynnshae]

@moodypanda130 Thank you for explaining that! Ugh....I was thinking..."Why 20?" ...anyways, thank you again for explaining it :-D

[jonvrgs]

@TheHotepsekhemwy u have to reduce!!!!!!!!!!

[alelicutie]

@TheHotepsekhemwy lowest term :)

[Rebirth3362]

@TheHotepsekhemwy you dont have to divide by 20 that was just her example:however it would take less time if u divide by a bigger number.

[TearInstitute]

@TheHotepsekhemwy

You divide by 20, because they are in the same times table. Are they not? 20x4=100 20x2=40.

Therefore you can divide, to simplify the fraction.

[TheZeldarion]

@TheHotepsekhemwy TO FIND THE LOWEST TERM OR TO SIMPLIFY 40/100 WHICH IS 2/5, WHICH IS 40/20=2 AND 100/20=5.

[tilinazaben]

@TheHotepsekhemwy Well , its because its the GCF of greatest common factor

[ThaoPhu999]

@TheHotepsekhemwy IKR! What about the GCM or GCF?!

[EpicEarn]

@TheHotepsekhemwy Because that's simplifying it. You're converting it into lowest terms by doing that and making it easier to work with. 2/5 is equal to 40/100.

[chris2011378]

@TheHotepsekhemwy

it' called smplifying....

[xPolymerClay]

@TheHotepsekhemwy Because that is the highest number you can reduce it by, Hope it helped! :]

[Skylighter6978]

@TheHotepsekhemwy Because of you divide it by a lower multiple, you still have to simplify. So it's just easier to dit by 20.

[d1995a3]

@TheHotepsekhemwy "Bwecuz it's not in lowiz termzz."

[LukasSkywalker1000]

@TheHotepsekhemwy The fraction need to be put into lowest terms alot of tests ask for this how ever though you can only do this if you can divide the number by half.

[MisterRavenclaw]

@TheHotepsekhemwy It will give the lowest common denom.

[ChristopherGiannone]

@TheHotepsekhemwy Because it is the greatest common divisor meaning the biggest number they both can be divided by.

[photogmommy86]

@TheHotepsekhemwy highest common number(factor)

[purpleglittermega]

@TheHotepsekhemwy because 20 is the gcf (greatest common factor) out of two of those numbers thats why

[Cavin21]

why cunt hurts for watching this, it's so hard more than calculus

[SabGotSwag5]

why do all these people from ''yourteachermathhelp'' sound like robots?

[ROBOTWWARRIOR]

@allstarwebkinz38 the number 10 upwards you put over 100 but say a single unit you put out of 10

so 40/100 3/10

[huddyhudd1]

@allstarwebkinz38 yeah

[trumpet603]

why so serious?

[harry811]

40% 40/100 Cancel out the 0 in 40,and cancel out 0 in the 100 4/10 which is 2/5

[harry811]

40% 40/100 Cancel out the 0 in 40,and cancel out 0 in the 100 40/10 which is 2/5

[acniloj]

how did you get 20??

[delaney4708]

@acniloj 20 can go in 40 and 100 hope this helps :)

[rexy670]

this teacher is great at math

[hackettisaiah]

how do i do it if its 37.5%

[GhEttOEthi0pianAnGel]

@MattANWO ♥ If ur making fun of her face. It's still her Dumbass. So STFU with ur comments you sound dumb♥

[filipe3441]

how did you got 20 please answer me i have a teat tomorow

[Jaydenstark320]

@filipe3441 you half 40 which is 20 :)

[cubscursed]

uhhh hello! an explanation of how you came up with 'divide by 20' would be helpful! why 20?

[brandonbeckster]

OMG SHE LOOKS LIKE NANNY MCPHEE

[GhEttOEthi0pianAnGel]

♥OMG SO WHAT IF HER FUCKEN FACE LOOKS EVIL OR MEAN. Ur not here to make FUN of her ass. ur here to learn. Grow-up losers. She's smart. Ok and thats that. Geeez♥

[fjordtru]

@GhEttOEthi0pianAnGel All teachers are good so yeah she's smart. I gotta admit. Lots of teachers posting their videos are smart, they just teach in a different way.

[SnazzyPredz]

@GhEttOEthi0pianAnGel :\

[timothy2533]

her face did look mean LOL

[julio10398]

i have a test tommorow

[SethMcFartlane]

Blink twice if you are being held hostage.

[masterghul]

Very helpful.:)

She is probably looking that way 'cuz she is sick of teaches us 'tards..lol

[QP4ozHP8oz]

@masterghul hell yeah,you people are dumb as hell...just drop out loser and grill my big macs.

[mathmatchpoint]

If you want to become good at math go to my youtube channel: (Mathmatchpoint). In my channel I will teach you everything about math step by step. I will start with teaching you (The Important basic math skills) and then I will teach you the more advanced math topics. Just click on Playlists when you are on my channel and you will be able to watch my math videos in order. I promise that I will teach everything in an easy way. Math is easy if you have a good teacher.

[Flashe007]

i have test tomorrow i hope i pass

[Neofcon]

Yeah, but where do you get the 20 from? 

[meg140140]

@Neofcon That's the Greatest Common Factor, 20.

[Neofcon]

@meg140140 Yeah, I figured it out earlier, but thats true. Thanx.

[sungod1019]

How the hell would you IDIOTS know if JC was good at math or not. Do you have a time machine that the world is not aware of ??? Am all for openly expressing what your thinking, but when your stupid like idiots who think they know how smart a person that they never meet before, then you idoits need to keep your presumption to yourselfs as well as your genetic gene code !!!

[sungod1019]

LOL why SO serious!!!

[girlygreen12]

I hate Harry Potter! I did not say he was god @ Math even tho he knows everything! Haven't you been to church. You think you know everything!

[girlygreen12]

never mind i looked at another vid at now i understand perfectley! thank you and God bless! WHO'S THE MAN!  JESUS! JOHN:3:16 For God so loved the worldthat he gave his one and only begoten son, that whosoever beleiveth i him shall not perish but have everlasting life. JOHN 3:16!

[Qermaq]

@girlygreen12 Jesus sucked at math and the Bible is for Harry Potter losers who cannot figure out that killing one another is wrong.

[kev0001000]

@Qermaq An example of an irrelevant comment posted by another idiot on youtube. Congrats dummy.

[Qermaq]

@kev0001000 Thank you. As a dummy, I accept your lavish prize. gitlygreen12 is the one who posted irrelevantly. I rather posted irreverently.

[kev0001000]

@girlygreen12 You know using your Saviors name in situations where it doesn't apply is pretty close to blasphemy. You're just making religious people look crazy. You can be religious and not go around shouting out hallelujah all the time. Unless of course you have been previously found in the crowd on one of those televangelists programs where they sell you healing in a tiny plastic container.

[girlygreen12]

You do not explane much. and you do not say why you put 20! not helpful

[RainyCityBoy]

and remember to speak trough your nose when speaking to make math even more boring.

[jesus77755]

Great job!! ...outstanding teacher. Keep up the good work. I usually get a whole

lot from your teaching videos.

[weezy825]

@starzy94. because you want to find the largest number that divides evenly into both 40, and 100. 20 is the number that you divide by to get 2/5. otherwise you would have to keep dividing by say, 2, or 10, and you would be putting more work on yourselves. :) hope that helped!

[blacklabel13131]

oh GOD, you damn idiots@ She isn't making these videos for you to jerk off to! If you learned something, that's all she probably cares to know.. not whether you think she's happy or not

[starzy94]

why divide by 20??

[ZXfuzEXE]

@starzy94 dats wat I dnt get lol

[nicholsjoshua15]

@starzy94 Because, you are just following the same steps you would follow if you were reducing a fraction. Go back and watch the video on reducing factions you will see what I mean. God bless you, and have a good one.

[chocfan101]

@starzy94 because then u get 2 20's to make fourty hope i helped

[Qermaq]

@starzy94 You gotta get OCD on LCD.

[AnimalLovaful]

omg wut the heck is up with her HANDS is 1 of them like handcuffed 2 he leg so every once in a while she puts her other hand bhind so it looks natural? and obviously this vid isnt viewed often bcuz the closest comment 2 today is 1 yr ago

[scath81]

instead of commenting bad..we shud have to knws how to thank people because they expose their face here just to help other people who are not good in math / slow learner..like we are...right..?the reason why we are here??and view this lesson..

[2smove4d]

why divide by 20

[kkk222able]

@2smove4d cuz thats the LCD of 40 and 100..... :P

[taksmurakano101]

why so serius???

[percyandmace]

finally. i have been struggling to remember. this is good and effective

[MrInfamous1984]

I like how she thinks she bad when she solves a problem.

[negativechriss]

she has no left hand, that's why she is hiding it. she has a claw instead. if u fail in calculation she will give u the claw oO

[ddiffenderfer]

Your videos are amazing! Smile and feel good!!

[AnimalLovaful]

@MaverickMuze hahah

[myspaceuser567]

im rdy for the FCAT now

[techdudes]

lol me too

[myspaceuser567]

well im back from school it im not kidding it was so easy im like wait is this 5th grade FCAT beacuse it was too easy it did not feel like 7th grade like its suppose to

[aj23s]

Y 100 ALL THE TIME

??????????

[o2FRESH4u]

@aj23s because....

[uberman53]

@PwnerBalooner and @lamani97

20 is the number that gets 40 and 100 to its lowest terms the first time, so it's easier.

[lamami97]

why by 20 i dont get it.?

[cuteboy4life34]

there both divisible by 20

[cocopuff520]

cause tht makes it in its lowerst term also wat do u do when u cant make it into lowersterm

[PwnerBalooner]

yea but why do u divide by 20? i dnt understand

[Kcb3512]

thx your the best you just help for my test thank you

[nodice100]

OLD BITCH !

[nodice100]

how about 110

[5959512]

this doesnt help when the number is like 83 or 67.

[mombasakul]

Thank you soo much for putting it in simpler terms.

[MarinesUSMCMarines]

i need help converting 24%

[nodice100]

*caugh* dumbass..... @MarinesUSMCMarines

[infidelguy]

You could also just simply the number by crossing out the extra zero between them. 40 over 100 becomes 4/10. least common fact between them is 2. 2x2 =4, 2x5=10. 2/5

[JoshHatch69]

how about 66 2/3

[gamer4life444]

listen 2 how she ses 20! LoL XD LoL

[lv4vintage]

she will always be despondent, they dont make enough money as they hsould be making...

[heyaaabceefghl]

why 20? x

[jenn1288]

because 20 is greatest common factor of 40 and 100

[heyaaabceefghl]

coool thanks x

[AtomicPhill]

ahh thanks also. i was just about to ask the same question.

[Hambidosvinet]

5 stars for the angry math face in the end, made me laugh :)

[KES59222]

just relax, u look so stern....doesn't look like you enjoy your job...

[DrattedOwnz]

its maths...

[MetalSwitch95]

STOP SAYING 'NOTICE'! ARGH!

[myrna609]

wth i dont get it

[LilJayz2]

kickyourass shut the fuck up you bitch. She helped me. Little bitch.

[Kickyourassjr]

go get layed u ugly whore

[COLONYPARK13]

lol u look depressed i was lookin 4 harder stuff tho thnx

[MNwildFranchise]

thanks!

[Armenianshifter]

THIS HELPED ALOT...THANX

[nickcarmy]

i already no this shit and im in grade 7

[wolfLink1234]

Then don't watch the video. Pop Quiz smart ass, If you know this stuff, then WHAT THE FUCK ARE YOU DOING WATCHING IT!!??

[NitekMuscle]

Good, now go and learn grammar.

[xxrochellemarie1xx]

kewl i got it thats um yea

[dmastadunk]

thanks!!!!

[yoknow3]

okkkkk

[Jenny102938]

thats easy because when i did that i saw 4/10 but it could simplify to 2/5 easy math cause it was both divisible by ten i just took away one 0 because it cant be 4/1 then that would change the whole problem so 4/10.....

[funkyboy90000]

man thats really easy now i wont fail my homework!!!!! freakin thank you man freakin thank you. no0 im kidding but it was really helpful.

[patevir1]

How did you come up with # 20 ?????

[tenzinpalden]

that's cuz you have to break your numbers in lowest trems and in this case both the dimoninator and numerator are divisible by 20.
