In this worksheet, we will learn how to find the difference between two decimal numbers.

*For Example:*

Find the difference between 17.5 and 2.75.

__Answer:__

**Finding the difference means subtracting**, so we need to work out **17.5 - 2.75**

Step 1. Line up the decimal points and add zeros when needed, next to the 17.50.

Step 2. Subtract, starting with the hundredths place. We need to exchange, so 5 in the tenths place becomes 4 and 0 in the hundredths place becomes 10. Subtract 10 - 5 = 5.

Step 3. Move to the tenths place and exchange with the ones place (to the left of the decimal), so the 7 becomes 6 and the 4 in the tenths place becomes 14. Subtract 14 - 7 = 7.

Step 4. Move to the ones place, to the left of the decimal. Subtract 6 - 2 = 4 and then in the tens place, 1 - 0 = 1.

The answer is **14.75.**

Subtract as normal, but remember to **line up the decimal points **so that the place value in the answer is correct.
