Solution - Long subtraction
14.3
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 5 | . | 2 | |
| - | 0 | . | 9 | |
| . |
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 1 from the digit (5) in the next number place which becomes (4) and get (12).
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| - | 0 | . | 9 | |
| . |
Subtract the numbers in the tenths column from the top number:
12-9=3
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| - | 0 | . | 9 | |
| . | 3 |
Subtract the numbers in the ones column from the top number:
4-0=4
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| - | 0 | . | 9 | |
| 4 | . | 3 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| - | 0 | . | 9 | |
| 1 | 4 | . | 3 |
The solution is: 14.3
