Soluzione - Long subtraction
0,9
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 0 | , | 5 | |
| - | 9 | , | 6 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the tenths column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (15).
| Place value | tens | ones | . | tenths |
| 0 | 15 | |||
| 1 | 0 | , | 5 | |
| - | 9 | , | 6 | |
| , |
Subtract the numbers in the tenths column from the top number:
15-6=9
| Place value | tens | ones | . | tenths |
| 0 | 15 | |||
| 1 | 0 | , | 5 | |
| - | 9 | , | 6 | |
| , | 9 |
Subtract the numbers in the ones column from the top number:
9-9=0
| Place value | tens | ones | . | tenths |
| 0 | 15 | |||
| 1 | 0 | , | 5 | |
| - | 9 | , | 6 | |
| 0 | , | 9 |
Write 0 in the tens place.
| Place value | tens | ones | . | tenths |
| 0 | 15 | |||
| 1 | 0 | , | 5 | |
| - | 9 | , | 6 | |
| 0 | 0 | , | 9 |
The solution is: 0,9
