Answer 1

$\rule{180}2$

$\rule{180}2$

Question :-

$\sf{\dfrac{-2}{7}+\dfrac{-3}{7}=\rule{20}{0.5}\ \times \dfrac{-3}{7} }$

Solution :-

Let the required number be y.

$\sf{\implies \dfrac{-2}{7}+\dfrac{-3}{7}=y \times \dfrac{-3}{7} }$

$\displaystyle{\sf{\implies \frac{-2}{7}-\frac{3}{7}=\frac{-3y}{7} }}\\\\\displaystyle{\sf{\implies \frac{-2-3}{7} =\frac{-3y}{7} }}\\\\\displaystyle{\sf{\implies \frac{-5}{7}=\frac{-3y}{7} }}\\\\\displaystyle{\sf{\implies -5=-3y}}\\\\\displaystyle{\sf{\implies 3y=5}}\\\\\boxed{\displaystyle{\sf{\implies y=\frac{5}{3} }}}$

Final answer :-

$\sf{\dfrac{-2}{7}+\dfrac{-3}{7}=\mathbf{\underline{\dfrac{5}{3}}} \times \dfrac{-3}{7} }$

$\rule{180}2$
