Solution - Long subtraction
12.44
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (13).
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| . |
Subtract the numbers in the hundredths column from the top number:
13-9=4
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| . | 4 |
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (12).
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 12 | ||||
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
12-8=4
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 12 | ||||
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| . | 4 | 4 |
Subtract the numbers in the ones column from the top number:
4-2=2
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 12 | ||||
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| 2 | . | 4 | 4 |
Subtract the numbers in the tens column from the top number:
3-2=1
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 12 | ||||
| 2 | 13 | ||||
| 3 | 5 | . | 3 | 3 | |
| - | 2 | 2 | . | 8 | 9 |
| 1 | 2 | . | 4 | 4 |
The solution is: 12.44
