Solution - Long subtraction
24.92
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
7-5=2
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| . | 2 |
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (12).
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 12 | ||||
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| . | 2 |
Subtract the numbers in the tenths column from the top number:
12-3=9
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 12 | ||||
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| . | 9 | 2 |
Because the upper digit (0) in the ones 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 (10).
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 10 | ||||
| 0 | 12 | ||||
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| . | 9 | 2 |
Subtract the numbers in the ones column from the top number:
10-6=4
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 10 | ||||
| 0 | 12 | ||||
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| 4 | . | 9 | 2 |
Subtract the numbers in the tens column from the top number:
7-5=2
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 10 | ||||
| 0 | 12 | ||||
| 8 | 1 | . | 2 | 7 | |
| - | 5 | 6 | . | 3 | 5 |
| 2 | 4 | . | 9 | 2 |
The solution is: 24.92
