    *gasp* you mean you double posted??

    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?
    ok, quick review. multiplying fractions

    \frac ab \times \frac cd = \frac {ac}{bd}


    please, NEVER make the mistake and think \frac ab + \frac cd = \frac {a + c}{b + d}. that is wrong

    did you look at the rule i posted?

    \frac 56 \times \frac 44 = \frac {5(4)}{6(4)} = \frac {20}{24}

    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 = ........?

    answer expl

    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

    this is not "cross multiplying", it's just regular multiplying

    ok, you seem to get it

    so, what's 7/5 - 3/4 = ?
