Question

459. 1) 5/7:10 2)3/5:3 3) 8/11:6 4)12/35:12​

Answer 1

Пошаговое объяснение:

1)

$\frac{5}{7} \div 10 = \frac{5}{7 \times 10} = \frac{5}{70} = \frac{1 \times 5}{14 \times 5} = \frac{1}{14}$

2)

$\frac{3}{5} \div 3 = \frac{3}{5 \times 3} = \frac{3}{15} = \frac{1 \times 3}{5 \times 3} = \frac{1}{5}$

3)

$\frac{8}{11} \div 6 = \frac{8}{11 \times 6} = \frac{8}{66} = \frac{4 \times 2}{33 \times 2} = \frac{4}{33}$

4)

$\frac{12}{35} \div 12 = \frac{12}{35 \times 12} = \frac{12}{420} = \frac{1 \times 12}{35 \times 12} = \frac{1}{35}$
