Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 5 | 6 | . | 3 | 5 | |
| 1 | 1 | 5 | . | 3 | 6 | |
| - | 7 | 5 | . | 9 | 6 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) 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 (15).
