Answer 2

Răspuns: $\bf \red{\boxed{\bf \dfrac{5}{24}}}$

Explicație pas cu pas:

$\bf -\dfrac{2}{5} \cdot\dfrac{3}{4}\cdot\bigg(-\dfrac{25}{36}\bigg)=$

$\bf -\dfrac{\not2}{5} \cdot\dfrac{3}{\not4}\cdot\bigg(-\dfrac{25}{36}\bigg)= -\dfrac{1\cdot3}{5\cdot2} \cdot\bigg(-\dfrac{25}{36}\bigg)=$

$\bf -\dfrac{3}{10} \cdot\bigg(-\dfrac{25}{36}\bigg)= \dfrac{\not3}{\not10} \cdot\dfrac{\not25}{\not36}=$

$\bf \dfrac{1}{2} \cdot\dfrac{5}{12}=\red{\boxed{\bf \dfrac{5}{24}}}$
