Subtracting Decimals
Subtracting decimals is easy if you keep your work neat
To subtract decimals, follow these steps:
- Write down the two numbers, one under the other, with the decimal points lined up.
- Add zeros so the numbers have the same length
- Then subtract normally, remembering to put the decimal point in the answer
Example: Subtract 0.03 from 1.1
| Line the decimals up: |
|
|
1.1 |
| |
|
- |
0.03 |
| |
|
|
|
| "Pad" with zeros: |
|
|
1.10 |
| |
|
- |
0.03 |
| |
|
|
|
| Subtract: |
|
|
1.10 |
| |
|
- |
0.03 |
|
|
|
|
| |
|
|
1.07 |
So, that was just like 110 - 3 = 107, but with the decimal point in a different position
Example: Calculate 7.005-0.55
| Line the decimals up: |
|
|
7.005 |
| |
|
- |
0.55 |
| |
|
|
|
| "Pad" with zeros: |
|
|
7.005 |
| |
|
- |
0.550 |
| |
|
|
|
| Subtract: |
|
|
7.005 |
| |
|
- |
0.550 |
|
|
|
|
| |
|
|
6.455 |
And that was just like 7,005 - 550 = 6,455
