Adding Decimals

Worksheet Objective: There are multiple worksheets that cover decimals. When you complete this one, be sure to move on to the next. |
The Introduction to Decimals worksheet covered place values, converting decimals to fractions, converting fractions to decimals, comparing decimals, and rounding decimals. If you are not familiar with these topics and have not yet done the first worksheet, you should probably go back to do it before you begin this worksheet.
Adding decimals
To add decimals, first line them up with point under point. Remember that any whole number is understood to have a decimal point at its right.
Example: 2.46 + 0.005 + 16 =
Step 1: Line up point under point. Notice the decimal point
after the whole number 16.
2.46
0.005
+16.____
Step 2: Add the numbers.
2.46
0.005
+16.____
18.465
Try some:
1. 0.8 + 0.047 + 0.36 =
2. 123 + 2.6 + 9.04 =
3. 9.043 + 0.27 + 15 =
4. 0.849 + 1.6 + 73 =
5. 7.563 + 0.08 + 124.9 =
6. 12.3 + 0.908 + 6 + 4.25 =
7. 1.6 + 23 + 12.73 + 0.485 =
8. .005 + 12 + 1.2389 =
9. 9.4 + 3.5 + 12.9007 =
10. 0.023 + 0.12 + 0.007 =
