well find the common factor and cancel out, i would start with 2, if 2 doesn't factor out of both, then i'll move on to 3, until i find a common factor

Ok got it, and so my objective would be to make sure that both the numerator and the denominator are divided by the same number?

sasogeek · Answer

yes, and once u do that, find out what the result of both the numerator and denominator are when u divide them, the answer will come smiling at you :) trust me

ja1 · Answer

Ah I see, thanks a bunch I had forgotten how to do this xD

sasogeek · Answer

it's tricky though, don't jump to conclusions after dividing, some multiplication is involved to find the right answer
