Solution - Long subtraction
29.95
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
7-2=5
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| . | 5 |
Because the upper digit (6) in the tenths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (16).
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 16 | ||||
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| . | 5 |
Subtract the numbers in the tenths column from the top number:
16-7=9
| Place value | tens | ones | . | tenths | hundredths |

| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| . | 9 | 5 |
Because the upper digit (7) in the ones 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 (17).
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 17 | ||||
| 7 | 16 | ||||
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| . | 9 | 5 |
Subtract the numbers in the ones column from the top number:
17-8=9
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 17 | ||||
| 7 | 16 | ||||
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| 9 | . | 9 | 5 |
Subtract the numbers in the tens column from the top number:
4-2=2
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 17 | ||||
| 7 | 16 | ||||
| 5 | 8 | . | 6 | 7 | |
| - | 2 | 8 | . | 7 | 2 |
| 2 | 9 | . | 9 | 5 |
The solution is: 29.95
