Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths |
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (15).
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 15 | ||||
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| , |
Subtract the numbers in the thousandths column from the top number:
15-7=8
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 15 | ||||
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| , | 8 |
Subtract the numbers in the hundredths column from the top number:
8-7=1
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 15 | ||||
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| , | 1 | 8 |
Subtract the numbers in the tenths column from the top number:
8-1=7
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 15 | ||||
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| , | 7 | 1 | 8 |
Subtract the numbers in the ones column from the top number:
3-0=3
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 15 | ||||
| 3 | , | 8 | 9 | 5 | |
| - | 0 | , | 1 | 7 | 7 |
| 3 | , | 7 | 1 | 8 |
The solution is: 3,718
