Question

Помогите решить 10,11

Answer 1

Пошаговое объяснение:

№10

$k \div \frac{10}{11} = \frac{2}{11} \div \frac{20}{11} \\ k \div \frac{10}{11} = \frac{1}{10} \\ k = \frac{1}{10} \times \frac{10}{11} \\ k = \frac{1}{11}$

№11

$0.05 \div x = 2 \frac{1}{3} \div 1 \frac{3}{5} \\ 0.05 \div x = \frac{7}{3} \div \frac{8}{5} \\ \frac{1}{20} \div x = \frac{35}{24} \\ \frac{1}{20} = \frac{35}{24} \times x \\ x = \frac{1}{20} \div \frac{35}{24} \\ x = \frac{6}{175}$
