Solution - Long subtraction
9.2
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 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| . |
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 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| . |
Subtract the numbers in the tenths column from the top number:
12-6-4=2
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| . | 2 |
Because the upper digit (4) in the ones 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 (14).
| Place value | tens | ones | . | tenths |
| 0 | 14 | |||
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| . | 2 |
Subtract the numbers in the ones column from the top number:
14-1-4=9
| Place value | tens | ones | . | tenths |
| 0 | 14 | |||
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| 9 | . | 2 |
Write 0 in the tens place.
| Place value | tens | ones | . | tenths |
| 0 | 14 | |||
| 4 | 12 | |||
| 1 | 5 | . | 2 | |
| 1 | . | 6 | ||
| - | 4 | . | 4 | |
| 0 | 9 | . | 2 |
The solution is: 9.2
