5,95
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | |
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths |
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
5-0=5
| Place value | ones | . | tenths | hundredths |
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | 0 |
| , | 5 |
Because the upper digit (7) 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 (17).
| Place value | ones | . | tenths | hundredths |
| 6 | 17 | |||
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | 0 |
| , | 5 |
Subtract the numbers in the tenths column from the top number:
17-8=9
| Place value | ones | . | tenths | hundredths |
| 6 | 17 | |||
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | 0 |
| , | 9 | 5 |
Subtract the numbers in the ones column from the top number:
6-1=5
| Place value | ones | . | tenths | hundredths |
| 6 | 17 | |||
| 7 | , | 7 | 5 | |
| - | 1 | , | 8 | 0 |
| 5 | , | 9 | 5 |
The solution is: 5,95
