Soluzione - Long subtraction
5,5
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths |
| 7 | , | 9 | |
| 0 | , | 5 | |
| - | 1 | , | 9 |
| , |
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 (7) in the next number place which becomes (6) and get (19).
| Place value | ones | . | tenths |
| 6 | 19 | ||
| 7 | , | 9 | |
| 0 | , | 5 | |
| - | 1 | , | 9 |
| , |
Subtract the numbers in the tenths column from the top number:
19-5-9=5
| Place value | ones | . | tenths |
| 6 | 19 | ||
| 7 | , | 9 | |
| 0 | , | 5 | |
| - | 1 | , | 9 |
| , | 5 |
Subtract the numbers in the ones column from the top number:
6-0-1=5
| Place value | ones | . | tenths |
| 6 | 19 | ||
| 7 | , | 9 | |
| 0 | , | 5 | |
| - | 1 | , | 9 |
| 5 | , | 5 |
The solution is: 5,5
