Find using appropriate properties: 3/7 * - 5/6 - 5/7 - 5/12 * 3/7​

Answer 1

Answer:

$\large\green\star\mathtt\orange{Solution}\green\star$

$\longrightarrow$ $\dfrac{3}{7} \times \dfrac{- 5}{6} - \dfrac{5}{7} - \dfrac{5}{12} \times \dfrac{3}{7}$

$\Rightarrow$ $\dfrac{- 15}{42} - \dfrac{5}{7} - \dfrac{15}{84}$

$\Rightarrow$ $\dfrac{- 30 - 60 - 15}{84}$

$\Rightarrow$ $\dfrac{- 90 - 15}{84}$

$\Rightarrow$ $\cancel{\dfrac{- 105}{84}}$

$\Rightarrow$ $\dfrac{5}{4}$

$\Rightarrow$ $1.25$

$\therefore$ $\sf The\: answer\: of\: this\: question\: is\: 1.25$
