Question

5/7×21/15:9/24
4/5:8/10:20/2
​

Answer 1

Ответ:

$\frac{5}{7} \times \frac{21}{15} \div \frac{9}{24} = \frac{5}{7} \times \frac{21}{15} \times \frac{24}{9} = \frac{1}{1} \times \frac{1}{1} \times \frac{8}{3} = 1 \frac{2}{3}$

$\frac{4}{5} \div \frac{8}{10} \div \frac{20}{2} = \frac{4}{5} \times \frac{10}{8} \times \frac{1}{10} = \frac{1}{1} \times \frac{1}{2} \times \frac{1}{5} = \frac{1}{10}$

Answer 2

Ответ:

Пошаговое объяснение:

1.

1) 5/7 * 21/15 = 1/1 * 3/3 = 3/3 = 1

2) 1 : 9/24 = 1 * 24/9 = 24/9 = 8/3 = 2. 2/3

2.

1) 4/5 : 8/10 = 4/5 * 10/8 =

1/1 * 2/2 = 2/2 = 1

2) 1 : 20/2 = 1 * 2/20 = 2/20 = 1/10
