Solution - Long subtraction
9.5
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 4 | |||
| - | 4 | . | 5 | |
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths |
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (10).
| Place value | tens | ones | . | tenths |
| 3 | 10 | |||
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| . |
Subtract the numbers in the tenths column from the top number:
10-0-5=5
| Place value | tens | ones | . | tenths |
| 3 | 10 | |||
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| . | 5 |
Because the upper digit (3) 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 (13).
| Place value | tens | ones | . | tenths |
| 0 | 13 | |||
| 3 | 10 | |||
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| . | 5 |
Subtract the numbers in the ones column from the top number:
13-4=9
| Place value | tens | ones | . | tenths |
| 0 | 13 | |||
| 3 | 10 | |||
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| 9 | . | 5 |
Write 0 in the tens place.
| Place value | tens | ones | . | tenths |
| 0 | 13 | |||
| 3 | 10 | |||
| 1 | 4 | . | 0 | |
| - | 4 | . | 5 | |
| 0 | 9 | . | 5 |
The solution is: 9.5
