Question

Выполните деление 2/3:14/15, 4/5:8, 21:7/8, 1/2:9, 3/28:/7,

Answer 1

Ответ:

$\frac{2}{3} \div \frac{14}{15} = \frac{2}{3} \times \frac{15}{14} = \frac{5}{7}$

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

$21 \div \frac{7}{8} = 21 \times \frac{8}{7} = 24$

$\frac{1}{2} \div 9 = \frac{1}{2} \times \frac{1}{9} = \frac{1}{18}$

$\frac{3}{28} \div \frac{1}{7} = \frac{3}{28} \times 7 = 12$
