Question

1/3÷1/7 1/2÷1/4 2/3÷1/8 4/9÷5/18
​

Answer 1

Ответ:

$\frac{1}{3} \div \frac{1}{7} = \frac{1}{3} \times 7 = \frac{7}{3} = 2 \frac{1}{3} \\ \frac{1}{2} \div \frac{1}{4} = \frac{1}{2} \times 4 = 2 \\ \frac{2}{3} \div \frac{1}{8 } = \frac{2}{3} \times 8 = \frac{16}{3} = 5 \frac{1}{3} \\ \frac{4}{9} \div \frac{5}{18} = \frac{4}{9} \times \frac{18}{5} = 4 \times \frac{2}{5} = \frac{8}{5} = 1 \frac{3}{5}$
