Question

$(-40)\times \_\_\_\_\_\_=80$. Fill in the blanks to make the statement true.

Answer 1

We have,$(-40)\times \_\_\_\_\_\_=80$

Let the value that must is multiplied is $a$.

$\begin{array}{rcl}(-40)\times a& =& 80\\ a& =& \frac{80}{-40}\\ & =& -2\end{array}$

Hence, the required answer is $-2$.
