When using long division to divide whole numbers, it's often appropriate to round the final answer.
For instance, let's find the value of rounded to the nearest tenth. We start by going through the long division procedure as usual:
We could divide further, but since we want to round to decimal place (the nearest tenth), we stop after finding the quotient to decimal places:
Finally, we round the quotient to the nearest tenth. The hundredths place is which is greater than so we round up:
Round the value of to decimal place.
We start by going through the long division procedure as usual:
We could divide further, but since we want to round to decimal place, we stop after finding the quotient to decimal places:
Finally, we round the quotient to the nearest tenth ( decimal place). The hundredths place is which is less than so we round down:

Abby wants to cut a inch piece of wire into four smaller pieces of equal size. How long should each piece be? Round your answer to decimal place.
To determine the length of each piece, we need to divide by
We start by going through the long division procedure as usual:
We went through all the digits and reached a remainder of , so the division is done.
Therefore,
Finally, we round the quotient to the nearest tenth ( decimal place). The hundredths place is which is greater than or equal to so we round up:
We conclude that each piece would be about inches long.

Round the value of to the nearest hundredth.
We start by going through the long division procedure as usual:
We could divide further, but since we want to round to decimal places (the nearest hundredth), we stop after finding the quotient to decimal places:
Finally, we round the quotient to the nearest hundredth. The thousandths place is which is less than so we round down:
