17,7
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 8 | , | 3 | |
| - | 0 | , | 6 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the tenths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (13).
| Place value | tens | ones | . | tenths |
| 7 | 13 | |||
| 1 | 8 | , | 3 | |
| - | 0 | , | 6 | |
| , |
Subtract the numbers in the tenths column from the top number:
13-6=7
| Place value | tens | ones | . | tenths |
| 7 | 13 | |||
| 1 | 8 | , | 3 | |
| - | 0 | , | 6 | |
| , | 7 |
Subtract the numbers in the ones column from the top number:
7-0=7
| Place value | tens | ones | . | tenths |
| 7 | 13 | |||
| 1 | 8 | , | 3 | |
| - | 0 | , | 6 | |
| 7 | , | 7 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths |
| 7 | 13 | |||
| 1 | 8 | , | 3 | |
| - | 0 | , | 6 | |
| 1 | 7 | , | 7 |
The solution is: 17,7
