Помогите решить примеры
1 1/2 +2 2/4
4 -2 1/4
7 -1 2/3
2 1/3-1 1/2
2 2/7 -1 3/5

Answer 1

1 1/2 + 2 2/4 = 1 2/4 + 2 2/4 = 3 4/4 = 4
4 - 2 1/4 = 3 4/4 - 2 1/4 = 1 3/4
7 - 1 2/3 = 6 3/3 - 1 2/3 = 5 1/3
2 1/3 - 1 1/2 = 2 2/6 - 1 3/6 = 1 8/6 - 1 3/6 = 5/6
2 2/7 - 1 3/5 = 2 10/35 - 1 21/35 = 1 45/35 - 1 21/35 = 24/35
