Question

The product of two integers is 72. If one of the integers is -12, what is the value of the other?

Answer 1

Let P be the unknown integer.

Given: Product of the integers = 72

One of the integers is -12.

$\Rightarrow$ P $\times$ (-12) = 72

$\Rightarrow$ P = 72 $÷$ (-12) = -6

(since 12 $\times$ 6 = 72 and when a postive number is divided by a negative number, quotient will be negative)

$\therefore$ The required number is -6.
