Code:

2/3 + 3/4 = N
(2*4)/(3*4) + (3*3)/(4*3) = N
8/12 + 9/12 = N
17/12 = N
N = 17/12 = 1+5/12

Code:

3/4 + N = 4/5
N = 4/5 - 3/4
N = (4*4)/(5*4) - (3*5)/(4*5)
N = 16/20 - 15/20
N = 1/20

[QUOTE=iLikeMoD;3057564]C. N - 3/5 = 1/4

Code:

N - 3/5 = 1/4
N = 1/4 + 3/5
N = (1*5)/(4*5) + (3*4)/(5*4)
N = 5/20 + 12/20
N = 17/20

You get the idea ... something might be wrong, I can't be bothered to check.

You should really learn this basic stuff, I think this is meant for like 8 year olds or something? /

THX FOR THAT!!!
