Common denominator: 24
Why: 4/8, 3/6, and 6/12 denominators are 8, 6, and 12. You will have to find the least common multiple of all these 3 numbers:
8: 8, 16, 24, 32
6: 6, 12, 18, 24, 30
12: 12, 24, 36
So 24 will be your common denominator.
If you need to solve the problem:
4/8 + 3/6: 4x6=24 8x3=24 8x6=48 24+24=48= 48/48
48/48 + 6/12: 48x6= 288 48x12= 576 48x12=576 288+576=864 = 864/576
Simplified: 3/2
