Answer 1

Ответ:

$\frac{3}{4} x = 12$

$x = 12 \div \frac{3}{4}$

$x = 12 \times \frac{4}{3}$

$x = 4 \times 4$

$x = 16$

/________

$3 \frac{3}{7} \div x = 1 \frac{5}{7} \\\\ x = 3 \frac{3}{7} \div 1 \frac{5}{7} \\ \\ x = \frac{24}{7} \div \frac{12}{7} \\ \\ x = \frac{24}{7} \times \frac{7}{12} \\ \\ x = 2 \times 1 \\ x = 1$
