Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths |
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | ||
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths |
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
6-0=6
| Place value | ones | . | tenths | hundredths | thousandths |
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| , | 6 |
Subtract the numbers in the hundredths column from the top number:
0-0=0
| Place value | ones | . | tenths | hundredths | thousandths |
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| , | 0 | 6 |
Because the upper digit (7) in the tenths 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 (17).
| Place value | ones | . | tenths | hundredths | thousandths |
| 0 | 17 | ||||
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| , | 0 | 6 |
Subtract the numbers in the tenths column from the top number:
17-8=9
| Place value | ones | . | tenths | hundredths | thousandths |
| 0 | 17 | ||||
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| , | 9 | 0 | 6 |
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | ones | . | tenths | hundredths | thousandths |
| 0 | 17 | ||||
| 1 | , | 7 | 0 | 6 | |
| - | 0 | , | 8 | 0 | 0 |
| 0 | , | 9 | 0 | 6 |
The solution is: 0,906
