Subtract the numbers in the hundredths column from the top number:
3-0=3
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 9 | 4 | . | 8 | 3 | 4 | |
| - | 3 | . | 0 | 0 | 0 | |
| . | 3 | 4 |
Subtract the numbers in the tenths column from the top number:
8-0=8

| 9 | 4 | . | 8 | 3 | 4 | |
| - | 3 | . | 0 | 0 | 0 | |
| 9 | 1 | . | 8 | 3 | 4 |
