Step-by-step explanation:

Here we need to estimated quotient of -23.514 and -3.98.

We need to use the division to find the answer.

Before going to the division, we need to estimate the dividend -23.514 and the divisor -3.98 to nearest integer.

-23.514, here the tenths place digit is 5, since it is greater than or equal to 5, we can 1 in the unit place and round off.

So, -23.514 = -24

-3.98, here the tenths place digit is 9 which is greater than or equal to 5, so we add 1 in the unit place and estimate.

So, -3.98 = -4

Now we have to divide -24 by -4.

Remember, when divide a negative by a negative number, the answer will be in positive. This is a division sign rule.
