  • what a load of rubbish, bad teacher. just divide 3 by 20 = 0.15. Then times by 100 = 15. Glad this woman wasn't at my school.

  • or you could multiply the whole thing by 5, which gets you 15/100, which equals to 0.15 which is equal to 15%

  • thank you now i found a shortcut to my math problems

  • Damn, she's not fuckin' around up there.

  • cool

    

  • now my problems even more confusing lol

  • Great Vid! Thanks

  • @yourteachermathhelp My question is 3/25 equals to what percentage can you guys help?

  • @Knicksboy792 In my opinion, the easiest way to turn fractions to percents is to divide the numerator(top number) by the denominator(bottom number). When you divide 3 by 25, you get 0.12. Now, you move the decimal place two places to the right. This gives you 12. Therefor, 3/25=12%

  • @Knicksboy792 just divide the 25 with 100 that gets you 4 and then multiply your problem with 4 which gets you 12/100, so the answer is 12%

  • lol

    

  • this is deadly thanks woman

  • For the love of God - smile!!!

    

  • the example in the video was 3/20. What times 20=100? 5 right. now do 3 x 5=15. so it is 15%

    For another example 4/25. 25 times what = 100. 4 right. now do 4 x 4=16 so its 16%

  • For everyone who is confused, the N represents an unknown number. Like what is the percentage of 32 out of 160, 160=n because it has not yet been solved, its best to just put nothing there. now just multiply 32 a 100 times, which would be 3200, now you divide your original denominator (160) by 3200. Which is 20. SO! N=20, so 32 is 20% of 160. its quite simple, its just the letter confused you guys.

  • whoa! im confused!

  • This didn't help me at all.

  • What the hell did I go to school for if I could learn this in 1:37?

  • @TheWakeOfRedemption the US school system sucks!! I am moving to China then coming back before they shut off my internet..

  • @TheWakeOfRedemption

    School curriculum and pace are set so even the biggest retard is given an equal chance to learn what the more fortunate students can pick up in less than a few minutes.

    This way intelligence can never used as a measurement of status.

  • @666nargarothfreak666::This is simple ,she just explained it in a bad way .N dosent mean anything ,she just put it there random so u dont even need it .i dont use it and i get the right awnser .so you know how she cross multiplied 3 and 100 and got 300 ?do long division and divide 300 and 20(and 20 is the number below the 3 ,wich u must divide that number)then when your done dividing ,you get 15 as an awnser and just add a % to 15 .awnser:15%

  • @IHeartSimss2

    Aha thanks mate:)

    no i get it :)

  • What is N and where do you get the 15 From?

    this is to confusing -.-

  • @666nargarothfreak666 i hear u brotha

  • you could just change into decimal and move the decimal over. much easier

  • da fuk... 0_0

  • what is n???????

  • Were the hell did the 15 come from

  • @miguel6248

    300/20 = 15... but i think this video just confused me more. I learned a different way to do it, now i don't remember either lol.

  • @miguel6248 u have to find what gives you 300 when you multiply 20 so 20 X 15 =300 so the answer is 15

  • What?

  • В данном видео полно нерациональных действий.Все можно гораздо проще сделать! И нашлибы более симпатичного преподавателя, к тому же голос у нее странный...

  • В данном видео полно нерациональных действий.Все можно гораздо проще сделать!

  • this video just making me boring because that's too easy

  • This chick needs a good hard fucking !

  • SHE LOOKS SO ANGRY ALL THE TIME LOLOLOL AND SHE TALKS LIKE A DAMN ROBOT!!!! LOL!

  • the way i do it is: if i have this sum to work with, i just multiply 20 with 5, and 3 with 5, and after that you just take away the denomenator completely and boom-theres your answer!

  • I don't understand what there is to dislike about these types of videos

  • @Derpster15 the sound of her voice 

  • idk what she is talking about

  • Can you divide also?!?

  • Would it kill her to smile? If you skip to 30 sec. she looks like she is sneezing! =)

  • NO NO NO SHE JUST CONFUSED ME WTF NO! -.- SOMEBODY HELP ME WITH THE N MESS UGHHH HATE MATHHHHH

  • why am i watching this? :L i already know this shit lmao

  • Comment removed

  • khanacademy look him up. hes alot of help, NIGGAS...LOL

  • she talks with so much attitude :i

  • Russian lady with an American accent

  • what happens if she gets a problem wrong? probably goes on a shooting rampage

  • ive got my GCSE in 4 days and my school made us do it 2 years early so this really helps :)

  • Damn this easy

  • I DONT GET WHERE THE 15 CAME FROM, ADD

  • @tyesha333 300/20 is 15.

  • @tyesha333

    3/20 times 5/5 is 15/100

    What you do on the denominator you must do on the numerator...

    You need a 100 for the denominator...so

    To get 100 on the denominator you multiply by 5 because 20 times 5 is 100

    Now do the same for the numerator, 3 times 5 is 15 so your answer is 15/100 which is 15% or 15 of a 100

  • waaw

  • multiply the whole damn thing by 5 and voila! 

  • @tttybhgf1 how

  • 10 bucks shes a virgin

  • Kahn's Academy is so easy to understand and the guy is the most awesome teacher, for anyone having trouble getting this! He is funded by Massachusetts Institute of Technology. Check him out for easy-to-understand Math! =]

  • @jeonzhou Too bad there are more lousy teachers than good ones in school..that's why I homeschool my children! I'm the lesser of the two evils! Blessings to you =]

  • @QP4oxHP8oz-- Hahah! Aren't you a treasure?!

  • rhanks i have ny math state test tmrow just reviewing

  • COOL!

    

  • I can always count on this girl xD

  • good guide

  • this girls voice is horrible

  • leave her alone she's hot. What a weird accent though.

  • she`s over dressed- she def wants me...

  • How the fuck you gone try to make me want some chess mix when Im trying to do my homework .

  • thank you so much... i really get it my teacher made it very confusing....... again i thank you

  • OMG THANK YOU! I GET IT NOW...... now... hopefully i dont 4get before the test.....

  • this ladys awsome

  • i rather do this

    3/20x5=15/100  =15%

  • I dont like this teacher she makes me mad

  • @mizzbabybee123 people who get mad easily start going bald in their early twenties.

  • haha

    woodhammath is MUCH MUCH BETTER!!!

    visit his youtube user account!!!

  • Thanks so much, I love this channel. It makes math soo quick and easy

  • Thank You SO MUCH! It Really Helped Me Undertand My Homework When i Actually Did It : ) Thanks!!!

  • Comment removed

  • confusing

    

  • NO HELP WATSOEVER

  • ok

  • this is so easy!!!!

  • Thank you for walking through the steps slowly, and making it easy to understand. Muchly appreciated.

  • test tommorow :(

  • @jeonzhou The purpose of math is not too see if you can get the right answer . They want to see if you can learn how to do something a certain way , and how well you can do it .

  • I had no clue how to do this five seconds ago . She explained it in terms I can understand . There are a LOT of these vids out there that explain them in different ways . Some of them will catch others wont .

  • Its more easy like this just-Divide the top of the fraction by the bottom,

    Then multiply the result by 100 and read off the answer !

  • her voice is so slow!

    

  • Thanks!!!!!

  • erghh this is making me so mad i have a test and my whole class was doing something different from this i think division and this vid is confusing me i am so frustrated im gonna cry !!!!!!!!!!!!!!!!!!

  • 3/20 x 100= 300/20 divide 20 and 300 and TADA 15%

  • okay well this sisnt help much

  • im scared of her face at the end she angry

  • go to 0.38 :p i am not even doing my gcse's ! im years before that! ; ((((((((

  • what if da denominator is 100 then wat do you do?

  • THIS ISH SO CONFUSING JEEZ

  • this just made me fucking depressed :/

  • @FireStoneMontage me too

  • @FireStoneMontage You need to grow up.

  • @JustinOsbo your commenting on something i wrote 4 months ago, well done sir! (Y)

  • Thank you for this help!!!

  • u can pu a proportion tree with 3/100 and x/20 multiply 3 by 20 then divide by 100

  • Dam Americans!!!  cant explain shit!!!!!!!!!!!

  • @Don27170 Racist =/

  • Where the fuck did the 15 come from crazy bitch.

  • @RainyCityBoy Take 20 and find out what it must be multiplied by to get 100 (which is 5, of course)

    Then, multiply 3 by 5 and you get 15.

    Tip: The number which the denominator is multiplied by should be the same number which the numerator is multiplied by (in this case, 5)

  • Stop making it complicating americans

  • you teaching methods are not practical, how did you get a teaching qualification

  • i bet she is very dominating in the bedroom :)

  • @trueChaos23 how do you know that where she lives even has a bed-rm?

  • @trueChaos23 stfu.

    you think women were use in sexually way?

    stfu you little new school pervert.

  • What they are not realizing with these videos, is that they need to teach as if showing a grade school kid. Giving a coligic explanation is useless, as college studens won't need this vid. Fraction fail!!

  • @99virgo Indeed.

  • Everyone has different ways / methods of solving problems it just depends on the statagy u use , at least she got the answer right though , but yeah why go through all of this when u can just do 3 divided by 20 which equals 0.15 WHich is the same as 15 percent

  • @Homiez4life619 Because if you are looking at this not knowing much about math ( such as myself ) I am not going to understand it . You are going to have to dumb it down for me so I can see what you did then I might can do what u did . I have not had this since high school . Who in there right mind is going to learn how to do this now days ? I mean since we have calculators .

  • u made it even more confusing

  • Fuck this shit im in 6th grade and this shit makes no sende WTF!!!u fucking britz

  • this was confusing just like all the other vidsman i need to pay more attention in school

  • I wonder if her job requires her to buy like a ton of different outfits. Shes wearing something different every time.

  • Lady, you made this way more compicated thatn its needs to be. You know 20 * 5 is 100 and what you do to the top you have to do to the bottem. so you do 20* 5 and 3* 5 and you get 15 over 100 which is 0.15 which is 15%.

    Learn to teach!

  • thanks ma'am your always the one that hekps me out. Those other man DON'T

  • 3/20=0.15

    0.15x100=15 %

    simple.

  • hmm, she has a point, if not a really pretentious one ^^; i mean i think htis sort of method would be best for more complicated fractions 7 over 82 and it would have to be a non calculator test too, other wise you could easily multiply the decimal figure by 100 by calculator or even just mov the bloody decimal point!!

    ...

    she has an annoying accent...

  • thanks this helped a lot

  • is she talking to us like were slow?

  • @MrCooldrive lol

  • she reminds me of robo cop

  • 20 time by 5 = 100. Then 3 time but 5 = 15. I could i have saved 1.37 mins of my life

  • omg thanks so much my math CRCT is tomorrow

  • thanks lol i taks test here i come

  • Damn she need to eat a tube of lard!!

  • 100/20=5

    5*3 = 15

    esay

  • emme s ugly

  • LoL it helped but its seems so hard to understand

    ???

    -_-

  • ah im in 6th grade and just started this so i was confused but thanks to you im not any more thanks!!!! :)

  • im in 7th lol

  • if any one is confused i have a simpler way.

    you just divide the numerator by the denominator and divide the answer by 100.

    this method works for all possible fractions.

    numerator=the top number in the fraction

    denominator=the bottom number in the fraction

  • Thanks! my teacher was teaching us this just the other day, didn't get it at all but thanks to you I know a lot simpler way to do it.

  • not exactly all you have to do is divide the percent over 100 and theres your answer duh!!!

  • the 300 came because she said 3 X 100 listen and you will hear it

  • This is just as bad as teachers I had in school.

    You have to go slower and lead the brain through each minimal step or else ppl get lost trying to figure all that out themselves while you're just jotting down at 100 mph. I understand it but I can't recommend this as help for a younger child.

  • I don't get it were did the 300 come frome

  • sorry but this made it very confusing! why not just divide 20 into 3 then move the decimal 2 places to the left? Why all the criss cross fancy crap!

  • Thanks man your the only reason why I understand my homework now, that lady did kind of make it confusing the way she cross multiplied

  • why she got 15?

    well 300 divided by 20 is 15,  i tried my calculator.

  • @tinyspecials i was exspecting all that then shes there going croos tblaahh n N i love Ns i was like look shut up lmao

  • Thats because it's a preparation for basic algebra.

  • @tinyspecials it was to divert your stupid ass...everyone else got it idiot.this lady is great!!!i like her.

  • Glad you can learn; good for you!

  • ????

  • where did the 300 came from

  • Pen Island = penisland = penis land

    i lerned math. lol

  • oh i see because alexander doesnt want to be stubborn he gets his degree from the toilet land of peanut island. ohhh ok thanks.

  • thanks!!!

  • i dont get it :(

  • @meezgirlmovies123 How do you not get that?!

  • She gets 15 because 20 goes into 300 15 times.

  • Just multiply the numerator and denominator by 5 each and you get 15/100 which is 15%. You multiply by 5 because 20x5 = 100.

  • where does she get 15 from?

  • thanks !!!!! i think i am gonna pass the test

  • thanks but were did the 15 come from

  • 30/2 = 15

    because 2(15)=30 :D

  • thank you=]

  • Thank you ! My homework was though !!!

  • 3:20=0.15x100=15

  • Can you show me how 6 1\4% = 1\16

  • you make it look so complicated when you just can multiply by 100% and get the answer in at the most 30 seconds!!!!!!

  • this is great , i actually passed my asvab thank you . By the way , i think your HOT! i

  • This is very helpful.thanks.
