Question

What should be multiplied by (-12) in order to get 180?

• A. 15
• B. -15
• C. 16
• D. -16

Answer 1

The correct option is B -15

Let the unknown number be $x$.
Then,
$\Rightarrow$ $x\times (-12)=180$
$\Rightarrow x=\left(\frac{180}{-12}\right)=-15$

$\therefore$ -15 has to be multiplied with -12 to get 180.
