Question

Find

(- 72) \div 9

and

72 \div (- 9)

Accepted Answer

We are given to find the value of $(- 72) \div 9$ and $72 \div (- 9)$

First, we shall divide the integers as the division of whole numbers without considering their signs. Then, we shall put a sign before the quotient.

When we divide a negative integer by a positive integer or a positive integer by a negative integer, we get, the quotient as a negative integer.

And, when we divide a negative integer by a negative integer, we get the quotient as a positive integer.

For example, $\frac{- 4}{2} = - 2$ and $\frac{- 8}{- 2} = 4$

Thus, we have, $(- 72) \div 9 = \frac{- 72}{9} = - 8$

And, $72 \div (- 9) = \frac{72}{- 9} = - 8$

Hence, the value of $(- 72) \div 9$ and $72 \div (- 8)$ are $- 8$ and $- 8$ , respectively.
