2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
5-0=5
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 8 | . | 1 | 2 | 5 | |
| - | 3 | . | 1 | 0 | 0 | |
| . | 5 |
Subtract the numbers in the hundredths column from the top number:
2-0=2
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 8 | . | 1 | 2 | 5 | |
| - | 3 | . | 1 | 0 | 0 | |
| . | 2 | 5 |
Subtract the numbers in the tenths column from the top number:
1-1=0
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 8 | . | 1 | 2 | 5 | |
| - | 3 | . | 1 | 0 | 0 | |
| . | 0 | 2 | 5 |
Subtract the numbers in the ones column from the top number:
8-3=5
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 8 | . | 1 | 2 | 5 | |
| - | 3 | . | 1 | 0 | 0 | |
| 5 | . | 0 | 2 | 5 |
Write 3 in the tens place.
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 8 | . | 1 | 2 | 5 | |
| - | 3 | . | 1 | 0 | 0 | |
| 3 | 5 | . | 0 | 2 | 5 |
The solution is: 35.025
