Division with Money
Like every other operation with money, division with money is a good introduction to dividing with decimals. The problems tend to be simple, but the decimal rules remain the same:
- Divide as usual.
- Make sure to line up answers and the dividend correctly.
- Bring the decimal up from the dividend into the answer.
Example:
$25.25 \div 5 = $
Write in "house" format (see lessons on Division (with remainders) or Division with decimals in the dividend for more).
$5)\overline{25.25}$
Divide the divisor into the dividend, digit by digit, writing the answer digit above the last digit of the portion of the dividend divided into.
$$\eqalign{&\;\; 5.05\\5)\!&\overline{25.25}\\ - & \underline{25}\\& \; \;02\\&\;\underline{-0}\\ & \;\;\;\; 25\\&\;\;\underline{-25}\\&\;\;\;\;\;\; 0}$$
When working with money, the decimal is almost always going to land two digits into the number, but the process of lining numbers correctly and bringing the decimal up is practice.
