2 2/7 × 5/8 = 10/7 = 1 3/7

5/7 × 0,2 = 5/7 × 2/10 = 2/14 = 1/7

23/28 × 0,14 = 23/28 × 14/100 = 23/28 × 7/50 = 23/200

1 4/16 × 1,12 = 1 4/16 × 1 12/100 = 20/16 × 112/100 = 7/5 = 1 2/5

Пошаговое объяснение:

2. 2/7 * 5/8 = 16/7 * 5/8 =

2/7 * 5/1 = 10/7 = 1. 3/7

5/7 * 0,2 = 5/7 * 2/10 =

1/7 * 2/2 = 2/14 = 1/7

23/28 * 0,14 = 23/28 * 14/100 = 23/2 * 1/100 = 23/200

1. 4/16 * 1,12 = 1. 4/16 * 1. 12/100 = 20/16 * 112/100 = 1/1 * 7/5 = 7/5 = 1. 2/5
