$\frac{ \frac{2}{5} }{x} = \frac{ \frac{1}{4} }{10}$
Doar rezolvarea, rezultatul trebuie să fie 16 ( $\frac{16}{1}$ )

Answer 1

$\frac{ \frac{2}{5} }{x} = \frac{ \frac{1}{4} }{10}$

$\frac{1}{4} \times x = \frac{2}{5} \times 10$

$\frac{x}{4} = \frac{2 \times 10}{5}$

$\frac{x}{4} = \frac{20}{5}$

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

$x = \frac{4 \times 4}{1}$

$x = 16$
