Răspuns: [tex]\bf \red{\boxed{\bf \dfrac{5}{24}}}[/tex]
Explicație pas cu pas:
[tex]\bf -\dfrac{2}{5} \cdot\dfrac{3}{4}\cdot\bigg(-\dfrac{25}{36}\bigg)=[/tex]
[tex]\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)=[/tex]
[tex]\bf -\dfrac{3}{10} \cdot\bigg(-\dfrac{25}{36}\bigg)= \dfrac{\not3}{\not10} \cdot\dfrac{\not25}{\not36}=[/tex]
[tex]\bf \dfrac{1}{2} \cdot\dfrac{5}{12}=\red{\boxed{\bf \dfrac{5}{24}}}[/tex]
