Question

Помогите пожалуйста решить дроби ​

Answer 1

Ответ:

1) 5/9 ÷ 3/5 = 5/9 × 5/3 = 25/27

2) 3/8 ÷ 3/5 = 3/8 × 5/3 = 5/8

3) 24/25 ÷ 12 = 24/25 × 1/12 = 2/25

4) 14 ÷ 7/8 = 14/1 × 8/7 = 16

5) 10/51 ÷ 15/68 = 10/51 × 68/15 = 2/3 × 4/3 = 8/9

6) 15/11 × 22/27 ÷ 25/7 = 14/45

1. 15/11 × 22/27 = 5 × 2/9 = 10/9

2. 10/9 ÷ 25/7 = 10/9 × 7/25 = 2/9 × 7/5 = 14/45

7) 8/25 ÷ 16/15 ÷ 5/4 = 6/25

1. 8/25 ÷ 16/15 = 8/25 × 15/16 = 1/5 × 3/2 = 3/10 = 0.3

2. 3/10 ÷ 5/4 = 3/10 × 4/5 = 3/5 × 2/5 = 6/25
