Question

Fill in the blanks to make the statements true.
______$\times \left(\frac{-2}{5}\right)=1$

Answer 1

Let x is the required number,
$\Rightarrow x\times \left(\frac{-2}{5}\right)=1$
$\Rightarrow \frac{-2x}{5}=1$
$\Rightarrow -2x=5$
$\Rightarrow x=\frac{-5}{2}$
Hence, $\frac{-5}{2}\times \left(\frac{-2}{5}\right)=1$
