Answer 1

Ответ:

$\frac{2}{9}x = \frac{5}{12} \\ 2x = 3.75 \\ x = 1.875$

$\frac{4}{15}y = \frac{2}{5} \\ 4y = 6 \\ y = 1.5$

$\frac{3}{5}x = 6 \\ 3x = 30 \\ x = 10$

$\frac{9}{10}y = 4 \frac{1}{2} = 9y = 45 \\ y = 5$

$\frac{3}{7}x = 1 \frac{4}{5} \\ 3 x = 12.6 \\ x = 4.2$

$\frac{7}{8}y = 14 \\ 7y = 112\\ y = 16$
