[nani5019]

Great!! gonna do it on exam day!!

[march12314]

71 is 10% of what number? 710. 71.0. Same with two digit numbers. 3.4 is 10% of what number? 34.

[darkness26532]

Great job!!! in example one we can 0.10 times by 80= 8 finish just that so easy!!!!!!!

[amri8418]

Yay I'm gonna get an +A on my test tomorrow thx!

[Liyah2sweet]

You make things super easy. I needed a refresher on decimals and you explained this way better than any teach I have ever had. I am going to favorite (I'm subscribing as well) this video for my younger brother when he needs help with math homework, thank you so much!!!

[northstar15]

@Liyah2sweet Thanks for this wonderful comment...and for subscribing!

[tenodogblu]

You are great, really helping me come to terms with stuff xx

[alleykateyes22]

Is this the only time you move once when you have 10% to get 5.5? I saw your other percent videos and you moved over twice? thx

[northstar15]

@alleykateyes22 when you are changing a decimal to a percent you always move the decimal 2 places to the right; when you are changing from percent to decimal, you always move the decimal 2 places to the left. I do not know what else you are referring to. You can give me a specific example if you want.

[TheOllie171]

I wish you were my teacher!!!!

[paparoni100]

very cool teaching , thanks man very clear.

[Raeb222]

Thank you for your videos. Will come back.

[SixtyDyingHearts]

omg thank you so much I was never able to learn this when I was in school, it's insane how easy you made it.

[RuinerPride]

Thank you, this is one of the most hardest things I needed helping with and YOU saved me sir. You're a great and wonderful teacher, I hope your my maths teacher, you're awesome! Thanks for the video, it helped me A LOT. :)

[blackandyellow53]

Thannk you, i am studying for the asvab and this will help me out to get a higher score

[northstar15]

@blackandyellow53 great--good luck!

[TheCheezWarrior]

Thanks you for this... it's kind of embarrassing for me to be a freshman in high school and still have trouble with percents... But this video helped. Thank you.

[Lalaloopsygirlz]

Thank you this was a great help to my 6th grader!

[goldenpink2008]

[MrsBieberlicious61]

Ty Ty Ty ty

[TheNavyleo]

Dude you made this so easy for me to understand I dunno why some teachers just yell cause we don't understand them. I understood you in four min and it less complicated thank you keep making new and different videos.

[northstar15]

@TheNavyleo thnx 4 this nice comment

[iDrStix]

We were doing a warm up review in algebra today and I completely forgot how to find the percent! thanks!

[ItouchezRock]

Thnx Easy r then I thought

[lovelylatina207]

THANK YOU! THIS VIDEO WAS GREAT! :)

[skyleena2]

thank you sooo much!!. this helpped me a lot. for 6 years i never understood how to work out percentages and not i was bothered to type it down on youtube. finally!! :D

[blackxangelxforever]

Who needs a tutor when u hav youtube?

[northstar15]

@blackxangelxforever I totally agree--ha ha

[EverMarie13]

Thank you so much for this!! Helped me alot,Thank you! :)

[patriciacarcass]

My whole life I always copied off the smart kid who was in all my classes in math and now I dont know why.

Thank you so much I really get it now!

[northstar15]

@patriciacarcass thnx 4 this comment

[patriciacarcass]

@northstar15 NO! thank you!

[luvbeingmama83]

do we round the 17.50 to 18 because that's what I did. Would that be considered wrong?

[northstar15]

@luvbeingmama83 rounding is not the same as changing a decimal to a percent--if you round 17.50 to the neatest whole number, then yes, the answer would be 18

[jesus77755]

Good teaching!

[9SuperMonkeyBall0]

I'm just kidding u'r not a retard, you an awesome teacher. Thanks for the tip.

[tan13t]

like the video can you show me how 2 do PYTHAGORS , BRACKETS, ANGLES, AREA AND PERMINETER

FROM tan13t

[northstar15]

@tan13t thanks for liking my vids--unfortunately, I do not have the time to make all the vids that you request, but let me think about some of these topics for future vids...

[SeeTimeRun391]

Thank you northstar, for taking the time to EXPLAIN the problems and the steps to solve them. What could've been a major shock to my tiny lizard math brain is now easy breezy. And, if you can make algebra understandable to me, then you have to win some kind of metal. ;)

[northstar15]

@SeeTimeRun391 thnx for the comment...

[Freeportku001]

Thi is too complicated ... just convert the 10% to 10 divide 100 and reduce that ...

[17lesliearies]

Are you serious? All this time I thought percentages were hard. Thanks dude I feel good about myself now. Lmao! Ty for not making it hard.

[Debedeb]

ty

[gleek1a1]

You made sense!, my teacher was like: nananannaaa.. Bah do this blah blah then you err... Banaaababaa, neneenenenene then you mulltnnipy dis numb I'n bah blah blah. Anyone know what that means? I don't! Lol but thanksso much 4 this ur a life saver!

[northstar15]

@gleek1a1 thnx 4 the comment...

[mizzbabybee123]

This so easy for me now! :]

[RanoPK]

You are a life saver. I wish you were my maths teacher.....

[devillord18]

The music intro reminded me of a retro game, I'm glad it wasn't a game video... as I need to revise.

[coolddp]

thanks xD

[zero117121]

Thank you

[quierovermasvideos18]

thank you very much you are a great teacher :)

[akamenace97]

Thanks a lot man you help me out on my homework.

[Zaimah1]

Where were you when I was in school, lol. Atleast my son, both of my sons have a chance to learn math in an easier, more simplified way, insuring more of their success. My mom used to always say... "Math is ALREADY easy". Now I am kind of feeling like it is.

[oripeoo]

thank so you so much!

[CHICAGOSFINEST2010]

Great!!!

[kalamatianoiendrash1]

thank you sooooo much!!!!

[HeadBounty]

thanks so much, but just to make sure i'm right,

62% of 40.. move the decimals 2 places to the left then multiply by 40. you should get the final answer as 24.80% right?

[northstar15]

That's exactly right. You can use mental math to check--50% of 40 would be 20, so 62% would be just a little more than this.

[victoreliasa]

what if you are trying to find the pecentage of 2 numbers like .180 is what percent of 394

[NitekMuscle]

So: 10% of X is always .X and 1% of N is .0X.

You can manipulate these values to arrive at any percentage. :)

[northstar15]

That's exactly right--you have it )

[avitar327]

Thank you so much. Even adults need help!!!

[JuStiNiSBleh]

fantastic!

[swordsman360]

TNX u for ur help I just started working with decimals today and u have cleared this up for me 100%TNX again!

[nucup98]

THx im in a 5th grade advanced math class super GREAT!!!

[MLGPRO1166]

super helpful...i was maaking this more harder then what it was

[benzmath]

good job

[migeru]

helpful :D

[goharejaz]

o oops nvm about the last comment i no now its going to be the same number beacuse 100% represents the whold number!So 100% of 20 is going to be 20! but thx again!last time i didnt watch the whold vidoe! so i didnt watch the part where u explained how to do 100%!

[goharejaz]

thx but i have a question what would you do if the persentage was 100%! for example 100% of 20 i know that (of) means to multiply in math! but how can u have a deciamal when its 100 do u just leave it as 100 and multiply it by 20 or do u do something else?

[jazzcraver]

thanks for your help. yourrrrrrrr great.

[ant1718]

thx it helps

[txluv5]

How would you do: 4% of what is 32?

[northstar15]

You can do it 2 ways: one way is to set-up a proportion that looks like this: 32/n = 4/100. Then, cross multiply the 32 and 100 to get 3,200. Then divide by 4.

Perhaps an easier way is to just divide 32 by .04 (you must change the 4% to a decimal). Either way, you get 800.

To check this, just multiply 800 by .04 and you will get 32.

[txluv5]

Thanks a lot for your help!

[AK47HEAVYMETAL83]

@northstar15 Nice! I knew how to find "what is % of whatever," but I never thought you could do the same with ("x% of what is 32 or whatever"), but by dividing lol I feel retarded now because I always fumbled when it comes to that type of equation (for years) lmao thanks a lot though!

[RanoPK]

@northstar15 wait a minute i'm getting 1.28 as my answer. Did i do it right?

[im4evaurzz]

nice shirt but u helped me lots of luv

[JTSuvier]

a Northstar, u r very correct. Pretty smart.

[fastfoodforce]

thanks i am makeing up work and it is like 2 am and im freaking tired but now i get it. Great vid :D

[UndestructableMass]

what if is was like 90% of 53

[northstar15]

Just change the percent into a decimal by moving the decimal two digits to the left (in 90% the decimal is at the right of the zero--it just isn't visible) and then multiply .90 and 53 to get 47.7. This makes sense because 90% is almost 100% and 47.7 is almost 53...

[UndestructableMass]

thanks bra

[CHR1SMS]

formula: eg. 23% of 54: 23x54 =1242 divide by 100= 12.42... 23% of 54=12.42 ?

is this right aswell?
