Question

1/2+1/4
2/3+1/6
5/8+5/24
1/2-1/8
2/3-4/9
3/4-1/12

Answer 1

1/2 + 1/4 = 2/4 + 1/4 = 3/4
2/3 + 1/6 = 4/6 + 1/6 = 5/6
5/8 + 5/24 = 15/24 + 5/24 = 20/24 = 5/6
1/2 - 1/8 = 4/8 - 1/8 = 3/8
2/3 - 4/9 = 6/9 - 4/9 = 2/9
3/4 - 1/12 = 9/12 - 1/12 = 8/12 = 2/3

Answer 2

2/3+1/6=5/6
5/8+5/24=20/24
и так далее
