Subtracting Fractions with Unlike Denominators

[kissy52808]

what happens when you have a fraction witha mixe number like this.

2 3/5 - 1/2

???

[northstar15]

@kissy52808 find the LCD, like I show in the video, then bring down your 2 for an answer of 2 and 1/10

[PoopingInTheBathtub]

Please answer. :( My difference was 3 4/9 but the choices are 4 2/9, 3 7/9, 4 7/9, and 4 2/6. Please help. =(

[101sallymay]

- you need to make more math videos ! :)

[beevang57]

[northstar15]

@ob913cupcake thnx for the comment--with the NEW YouTube, things can get confusing--I hope my vids continue o help...

[savcola]

What happened to the one you borrowed from five? I ask because you added 10 plus fifteen and got 25 and the proceeded to subtract 12 from 25? Was this an oversight on your part? Or did I miss something?

[321123454]

dude thaks i under stand my math homework now thanks so much

[ob913cupcake]

I will not remember this I'm in 5 grade grrr

Math I hate u sooo much!!!!:S

[BlazeX344]

[Chizboy101]

simply put.....

thanks man i luv u oh yah kickass um hum damn i need a life:)

[Chizboy101]

@Chizboy101 Funny

[Brock10000000]

For METHOD 2 (when taking whole numbers and changing them into mixed number), for the last step, I don't get how you were able to just subtract the numerators (85 - 57) and not subtract the denominators (3 - 5, which obviously you can't) but instead of that, you multiplied them? WTF? LOL. Besides that, great vid. I feel young again!

[northstar15]

@Brock10000000 well, it is very hard to explain via email. My suggestion would be to keep watching over and over and it should click... :)

[priprirocken]

Cant you just multiply the denominator n you would get 15 n than you take the whole number and multiply it by the numorator for both fractions n you would get the exact answer as yours isnt that much easier

[fangstrike1]

faster method is easier

[777sparkledk]

Thank you my teacher when my teacher explains it I don't get it!

[lilduner183]

Thank you!! 1 moment I was ripping hairs outta mah head outta stress now on not Ty

@foofooisawsome good luck!

[DreamerBieber]

I got it.. But why 25?? Look--> 2:00

[northstar15]

@DreamerBieber you are adding the num and denom of the top fraction and also keeping the denom of that fraction

[martinlego25]

I was way behind this! THANKS!!! I really like math when there is no pressure.

[djx457]

thanks this helped me alot

[canacaboy11]

dude thanks alot you really help me out :D

[dinodon1]

What if the numerator on top is smaller than the bottom numerator on a fraction that

doesn't have a whole number? Just subtract it ?

[caligonpictures]

thanks!

[WWElover331]

Thanks :)

[3rddegreetalent]

Thank you so much for the video it really helped me I'm in the 7th grade and I was behind on this stuff I GET IT NOW THANK YOU SO MUCH!!!

im looking this up because my teacher didnt know how to explain it

[1943majic]

awsome help i can see why the chidren are confused , trying to cram so much into thier small brains, thanks so much

[northstar15]

@1943majic agreed--thnx for the comment

[METALCOOLER117]

@1943majic actually, im 13 and im able to comprehend more things then adults can. it all depends on your teaching and if your willing to push yourself to the next level.

omg i was stuck on my homework thank you soooo much for re-teaching me clearly!

[eliybeats]

Thanks you so much!! I got confused because on the problem I was doing for homework I had two negatives so I ended up adding. But thanks for your tutorial. It helped alot.

[northstar15]

@eliybeats thanks for the comment...

[Assassinater22]

@eliybeats Thanks You?,i think you were to happy to type right :/

[eliybeats]

@Assassinater22 lol somewhat. Math is frustrating to me.

[Assassinater22]

by the way thanks for the video 

[coolstorybabexx]

i like the second step, thats what my teacher taught me :)

[pieisgoodHaHaHaHa]

@northstar1 i dont get why you just cant do 12-10 instead of 10-12 im kinda confused.

[northstar15]

@pieisgoodHaHaHaHa you cannot subtract a larger number from a smaller one without having the answer be negative

[cliffworks4321]

thanks i have to hep teach my Japanese children this stuff in Japanese it's much easier with your tutorial, and your speaking delivery is clear thanks.

[northstar15]

@cliffworks4321 you're welcome--check out my other vids

[cliffworks4321]

@northstar15 i will have 11 and 8 year old thanks.

[1prettydiva]

Thank you so much!! you really have no idea how much this helped im a straight D student and trying to improve my grades. Thanks :]

[IAMTHESURVIVAA]

i hate math but i dint want to fail it D':

[MUSICfreak5005]

thank you SO MUCH!!

wait i have a question: lets say you are subtracting or adding unlike denominators but WITHOUT a whole number? how do you do it? do you continue with the methods in this videos or does it change?

[morganlov]

thanks tht help a lot to me and my cousin and we still dont kinda get it but thnks anyway

[sportsfankyle16]

OMG Thank you so much

[ChannelNonsense]

thank god ur understandable

[PinkyPiePrincess18]

is it the same process without the whole numbers?

[northstar15]

@PinkyPiePrincess18 basically--if the denoms are different, you will need to find the LCD first, just like here, then continue.

[thedivinity24136]

You just taught me what my Mom, Dad, and Math Teacher couldn't.

[northstar15]

@thedivinity24136 fantastic--thnx 4 the comment
