Question

Выполните действие 1) 12/35:2/5 2) 8 3/4:2 1/3 3) 15/17:5​

Answer 1

1) 12/35 : 2/5 = 12/35 · 5/2 = (6·1)/(7·1) = 6/7

2) 8 3/4 : 2 1/3 = 35/4 : 7/3 = 35/4 · 3/7 = (5·3)/(4·1) = 15/4 = 3 3/4

3) 15/17 : 5 = 15/17 · 1/5 = (3·1)/(17·1) = 3/17

Answer 2

Давайте выполним указанные действия:

1. (12/35) ÷ (2/5) = (12/35) * (5/2) = (12 * 5) / (35 * 2) = 60/70 = 6/7.

2. 8 3/4 ÷ 2 1/3 = (8 + 3/4) ÷ (2 + 1/3) = (8 + 3/4) ÷ (2 + 3/3) = (8 + 3/4) ÷ (2 + 1) = (35/4) ÷ (3) = (35/4) * (1/3) = (35/12).

3. (15/17) ÷ 5 = (15/17) * (1/5) = (15/85) = 3/17.
