Question

$\frac{a}{b } = \frac{ak}{bk}$
subtruting proper number in the following
$\frac{5}{7} = \frac{?}{28} = \frac{?}{3.5}$
$\frac{9}{14} = \frac{4.5}{?} = \frac{?}{42}$

​

Answer 1

$\frac{5}{7} = \frac{\underline{\boxed{\sf{ 20}}}}{28} = \frac{\underline{\boxed{\sf{ 2.5}}}}{3.5} \\ \\ \frac{9}{14} = \frac{4.5}{\underline{\boxed{\sf{ 7}}}} = \frac{\underline{\boxed{\sf{27 }}}}{42}$
