Question

x/12=7/10
x/16=9/32
С ПРОВЕРКОЙ

Answer 1

1) $\frac{x}{12}=\frac{7}{10}$

$x = \frac{7*12}{10} = \frac{84}{10} = 8,4$

Проверка:

$\frac{8,4}{12}=\frac{7}{10}$

$\frac{8,4*50}{12*50} = \frac{420 : 60}{600 : 60} = \frac{7}{10}$

2) $\frac{x}{16 } = \frac{9}{32}$

$x = \frac{9*16}{32} = \frac{9}{2} = 4,5$

Проверка:

$\frac{4,5}{16 } = \frac{9}{32}$

$\frac{4,5*2}{16*2} = \frac{9}{32}$
