amistre64 · Answer

I would simply equate them to some unknown number:

1/2+1/4.= N  ; and let the math solve itself

1(2)/2+1(2)/4.= (2)N

1+1/2.= 2N

1(2)+1(2)/2.= 2(2)N

2+1= 4N

3= 4N

3/4= 4N/4

3/4= N

same steps; the process doesnt change; only the numbers that are used

anonymous · Answer

(1/4)*3 + (2/3)*4 
= 3/12+8/12 
= 11/12

amistre64 · Answer

1/4 + 2/3 = N

1(3)/4 + 2(3)/3 = (3)N

3/4 + 2 = 3N

3(4)/4 + 2(4) = 3(4)N

3 + 8 = 12N

11 = 12N

11/12 = 12N/12

11/12 = N
