Answer 2

Answer:

Given :-

$\longrightarrow$ $\bigg(\dfrac{25}{2} - \dfrac{21}{2}\bigg) ÷ \dfrac{4}{5} \:of\: \dfrac{2}{7} + 8$

Solution :-

$\longrightarrow$ $\bigg(\dfrac{25}{2} - \dfrac{21}{2}\bigg) ÷ \dfrac{4}{5} \:of\: \dfrac{2}{7} + 8$

$\Rightarrow$ $\bigg(\dfrac{25 - 21}{2}\bigg) × \dfrac{5}{4} × \dfrac{2}{7} + 8$

$\Rightarrow$ $\dfrac{4}{2} × \dfrac{5}{4} × \dfrac{2}{7} + 8$

$\Rightarrow$ $\dfrac{40}{56} + 8$

$\Rightarrow$ $\dfrac{40 + 448}{56}$

$\Rightarrow$ $\cancel{\dfrac{488}{56}}$

$\Rightarrow$ $\dfrac{61}{7}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: 8.714$
