Solution - Long subtraction
10.9
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 4 | . | 9 | |
| 0 | . | 7 | ||
| - | 3 | . | 3 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (9) 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 (19).
| Place value | tens | ones | . | tenths |
| 3 | 19 | |||
| 1 | 4 | . | 9 | |
| 0 | . | 7 | ||
| - | 3 | . | 3 | |
| . |
Subtract the numbers in the tenths column from the top number:
19-7-3=9
| Place value | tens | ones | . | tenths |
| 3 | 19 | |||
| 1 | 4 | . | 9 | |
| 0 | . | 7 | ||
| - | 3 | . | 3 | |
| . | 9 |
Subtract the numbers in the ones column from the top number:
3-0-3=0
| Place value | tens | ones | . | tenths |
| 3 | 19 | |||
| 1 | 4 | . | 9 | |
| 0 | . | 7 | ||
| - | 3 | . | 3 | |
| 0 | . | 9 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths |
| 3 | 19 | |||
| 1 | 4 | . | 9 | |
| 0 | . | 7 | ||
| - | 3 | . | 3 | |
| 1 | 0 | . | 9 |
The solution is: 10.9
