The Language of Mathematics (12): Multiply and Divide Fractions

[AnAngelsKisss]

I am confused Chycho, I have a problem of 30/10 (30 over 10) so the answer I got was 2/6 (2 over 6) Is that correct?

[chychochycho]

nope, the answer is 3.

[AnAngelsKisss]

@chychochycho idk this is really loosing me

[chychochycho]

take a look at videos 9, 10, and 11... they may help.

@AnAngelsKisss Where exactly do you get lost?

[AnAngelsKisss]

@MAJESTIcag7 I think it is the negative numbers. I am not used to going negative. I auto flip the numbers to create a positive. Idk exactly, I know this math just doesn't make sense to me. My husband says I try to comlicate it. I am searching for a reason why math does what it does.

[AnAngelsKisss]

@AnAngelsKisss I think I got this part. my thing that is getting me is order of operations that is whole numbers equaling a negative number. My Cpat retake is tomorrow @1pm

[chychochycho]

You're welcome, and good luck on the test :)

[mixolidianmode]

[mantis6sic6]

143/84 ends there because 143 is a prime number

[nubonamission]

[chychochycho]

you're welcome.

[IDIEIRIICIK]

[chychochycho]

[chychochycho]

Sweet! ... 83 most definitely works :)

[434504]

Thanks so much...I'm 63 and just learning this stuff. You have helped SO much. I have mid-terms coming but was completely frustrated. Thanks to you, I'm going to do get a much better grade. Onward to composite fractions! I'm sticking with you.

[chychochycho]

glad to help :)

[FlamingoTel]

Great teaching... But why are you fast forwarding through sections?

[chychochycho]

thanks FlamingoTel ... the reason i'm fast forwarding is because i've done a few videos about breaking down numbers into their prime factors so for this video its the procedure that was the main part, not breaking down the numbers.

keep in mind that i made a mistake in this video ... see notes on the side... I forgot to "kill a 7 in the brakedown of 35"

[eiriker]

In elementary school I learned that we must flip 44/28 as well, or else we wont' get the right answer.

[chychochycho]

thank for the correction. Great eye :)

i'll fix the mistake in the next couple of days. What i will end up doing is changing the -40 to -50 so it matches the answer.

thanks again, and it's really good knowing that the exercises are coming in handy :)

[mentor32]

Even though this way can get a little messy I think it's a good because you literally reduce it until you can't reduce it any more, which makes the final answer final.Oh yeah Lddstyx, thanx for pointing out that 7, I missed it too. Peace and Thanx

[LddStyx]

You forgot to kill a 7: the brakedown of 35

[chychochycho]

haha that i did ... shity :)

okay the final answer should be 143/12

thanks for the correction :)
