Solution - Long subtraction
5.2
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 1 | . | 7 | |
| 2 | . | 1 | ||
| - | 4 | . | 4 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the tenths column from the top number:
7-1-4=2
| Place value | tens | ones | . | tenths |
| 1 | 1 | . | 7 | |
| 2 | . | 1 | ||
| - | 4 | . | 4 | |
| . | 2 |
Because the upper digit (1) 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 (11).
| Place value | tens | ones | . | tenths |
| 0 | 11 | |||
| 1 | 1 | . | 7 | |
| 2 | . | 1 | ||
| - | 4 | . | 4 | |
| . | 2 |
Subtract the numbers in the ones column from the top number:
11-2-4=5
| Place value | tens | ones | . | tenths |
| 0 | 11 | |||
| 1 | 1 | . | 7 | |
| 2 | . | 1 | ||
| - | 4 | . | 4 | |
| 5 | . | 2 |
Write 0 in the tens place.
| Place value | tens | ones | . | tenths |
| 0 | 11 | |||
| 1 | 1 | . | 7 | |
| 2 | . | 1 | ||
| - | 4 | . | 4 | |
| 0 | 5 | . | 2 |
The solution is: 5.2
