Apply rule

a \cdot (- b) = - a \cdot b

\frac{2}{5} ((- 10)) = - \frac{2}{5} \cdot (- 10)

Apply rule:

- a (- b) = ab

- \frac{2}{5} (- 10) = \frac{2}{5} \cdot 10

= \frac{2}{5} \cdot 10

\frac{2}{5} \cdot 10 = 4

\frac{2}{5} \cdot 10

Convert element to fraction:

10 = \frac{10}{1}

= \frac{2}{5} \cdot \frac{10}{1}
