Solution - Long subtraction
1.7
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths |
| 5 | . | 2 | |
| 2 | . | 9 | |
| - | 0 | . | 6 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 2 from the digit (5) in the next number place which becomes (3) and get (22).
| Place value | ones | . | tenths |
| 3 | 22 | ||
| 5 | . | 2 | |
| 2 | . | 9 | |
| - | 0 | . | 6 |
| . |
Subtract the numbers in the tenths column from the top number:
22-9-6=7
| Place value | ones | . | tenths |
| 3 | 22 | ||
| 5 | . | 2 | |
| 2 | . | 9 | |
| - | 0 | . | 6 |
| . | 7 |
Subtract the numbers in the ones column from the top number:
3-2-0=1
| Place value | ones | . | tenths |
| 3 | 22 | ||
| 5 | . | 2 | |
| 2 | . | 9 | |
| - | 0 | . | 6 |
| 1 | . | 7 |
The solution is: 1.7
