Answer 1

Пошаговое объяснение:

№1

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

2) 2 1/8 * 4 = 17/8 * 4 = 17/2 * 1 = 17/2 = 8 1/2

3) 3 1/3 : 2 1/2 = 10/3 : 5/2 = 10/3 * 2/5 = 2/3 * 2/1 = 4/3 = 1 1/3

4) 8 1/2 + 1 1/3 = 8 3/6 + 1 2/6 = 9 4/6 = 9 2/3

№2

1) 2 4/9 + 1 1/6 = 2 8/18 + 1 3/18 = 3 11/18

2) 3 11/18 * 1 4/5 = 65/18 * 9/5 = 13/2 * 1/1 = 13/2 = 6 1/2

3) 3 1/9 : 2 1/3 = 28/9 : 7/3 = 28/9 * 3/7 = 4/3 * 1/1 = 4/3 = 1 1/3

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