Answer 1

Ответ:

$1) \frac{2}{9} x = \frac{5}{12} \\ x = \frac{3}{2} \times \frac{5}{4} \\ x = \frac{15}{8} \\ 2) \frac{4}{15} y = \frac{2}{5} \\ y = \frac{15}{4} \times \frac{2}{5} \\ y = \frac{3}{2} \\ 3) \frac{3}{5} x = 6 \\ x = 5 \times 2 \\ x = 10 \\ 4) \frac{7}{8} y = 14 \\ y = 8 \times 2 \\ y = 16 \\ 5) \frac{3}{7} x = 1 \frac{4}{5} \\ \frac{ 3}{7} x = \frac{9}{5} \\ x = \frac{21}{5} \\ 6) \frac{9}{10} y = 4 \frac{1}{2} \\ \frac{9}{10} y = \frac{9}{2} \\ y = 5$
