Erm.
This probably would be easy for you to answer. Well, you see, we're learning fractions. I'm the kind who doesn't pay attention in class. So.. well.. I know how to do it. the problem is, that the way my teacher tells us to do it is, well, a little.. hard for me to do. And confusing. So, my question is, can anybody give me their way of doing a multiplication problem with fractions? This is 6th grade math. It should be easy for you.. >.< Like this problem: 2/4 x 5/22 = __ My way is a little bit.. hard. so, I really want to have an easy lesson of doing it, so it could be easier for me.  Thank you. |

you multiply the numerator and denominator striaght across duh
it would be like multiplying the 2 stright across to the 5 and same with the denominator 2/4 x 5/22 = 10/44 |

It's actually 10/88. 4 x 22=88.

Edit because my last post made no sense:
Yeah, like gotnoheart said, Vietrice, you multiplied wrong. 4 x 22 = 88 Let me draw you a picture:

The answer isn't 10/88 if you're required to simplify it.
It should be 5/44 simplified. You could work work it like this, too: [attachment=11517:attachment] Simplify the problem so you don't have to simplify the answer.

Ahh, it's okay. I only pointed it out because I remember getting A LOT of points off for not simplifying the answers.

3 is the same as 3/1. So it would look like this:

Again, it's a lot quicker if you simplify the problem before working it out. That way, you don't have to simplify the answer.
[attachment=11518:attachment] Ah, thanks for not saying my numbers are messy.
