*gasp* you mean you double posted?? :eek:

that was very naughty of you, yellow! that's even more against the rules than not posting new questions in a new thread

you multiply the bottom so do you multiply the top?

you would get 5/24 is that right? or do i have to do more?

please, NEVER make the mistake and think . that is wrong - Sep 15th 2008, 06:49 PMyellowjello
so I'm right, the answer is 5/24

Correct? - Sep 15th 2008, 06:50 PMJhevon

ok, why go through all the trouble of turning 5/6 into 20/24 only to simplify it to 5/6 again? aren't you just going in circles? there is a reason for writing it as 20/24, we don't want to go back to 5/6. don't forget your objective. you want 5/6 + 1/4, you are not dealing with 5/6 alone, you are adding something to it. if you make the manipulations i told you, you end up with

5/6 + 1/4 = 20/24 + 6/24 = ........? - Sep 15th 2008, 07:27 PMyellowjelloanswer
26/24 or 13/12 right?

so you cross multiply 5*4 & 6*1 and multiply the denominators 24 underneath each of those numerators to get 20/24 + 6/24 then add them to get 26/24 and simplify to get 13/12
