Answer 1

Пошаговое объяснение:

№1

1) 4 - 2 5/6 = 3 6/6 - 2 5/6 = 1 1/6

2) 1 1/6 - 5/12 = 1 2/12 - 5/12 = 14/12 - 5/12 = 9/12 = 3/4

3) 7 1/12 - 5 3/4 = 6 13/12 - 5 9/12 = 1 4/12 = 1 1/3

4) 3/4 * 1 1/3 = 3/4 * 4/3 = 12/12 = 1

№2

1) 3 1/2 - 2 3/8 = 3 4/8 - 2 3/8 = 1 1/8

2) 4 1/3 - 1 5/6 = 4 2/6 - 1 5/6 = 3 8/6 - 1 5/6 = 2 3/6 = 2 1/2

3) 1 1/8 * 1 1/3 = 9/8 * 4/3 = 36/24 = 3/2

4) 3/2 * 2 1/2 = 3/2 * 5/2 = 15/4 = 3 3/4

5) 5 17/20 + 3 3/4 = 5 17/20 + 3 15/20 = 8 32/20 = 9 12/20 = 9 3/5
