8-0=8
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 7 | . | 2 | 8 | |
| - | 2 | . | 1 | 0 | |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
2-1=1
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 7 | . | 2 | 8 | |
| - | 2 | . | 1 | 0 | |
| . | 1 | 8 |
Subtract the numbers in the ones column from the top number:

| 2 | 7 | . | 2 | 8 | |
| - | 2 | . | 1 | 0 | |
| 5 | . | 1 | 8 |
Write 2 in the tens place.
