Question

What should we multiply with $\frac{11}{-7}$ to get $\frac{1}{2}$

Answer 1

$\text{let}x\text{is such number then}$

$\frac{11}{-7}\cdot x=\frac{1}{2}$

$\Rightarrow \frac{-11}{7}x=\frac{1}{2}$

$\begin{array}{c}\Rightarrow -11x=\frac{7}{2}\\ \Rightarrow x=\frac{7}{2}\times \frac{1}{-11}=-\frac{7}{22}\end{array}$
