Soluzione - Long subtraction
1,96
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the hundredths 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 (11).
| Place value | ones | . | tenths | hundredths |
| 0 | 11 | |||
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| , |
Subtract the numbers in the hundredths column from the top number:
11-5=6
| Place value | ones | . | tenths | hundredths |
| 0 | 11 | |||
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| , | 6 |
Because the upper digit (0) 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 (10).
| Place value | ones | . | tenths | hundredths |
| 6 | 10 | |||
| 0 | 11 | |||
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| , | 6 |
Subtract the numbers in the tenths column from the top number:
10-1=9
| Place value | ones | . | tenths | hundredths |
| 6 | 10 | |||
| 0 | 11 | |||
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| , | 9 | 6 |
Subtract the numbers in the ones column from the top number:
6-5=1
| Place value | ones | . | tenths | hundredths |
| 6 | 10 | |||
| 0 | 11 | |||
| 7 | , | 1 | 1 | |
| - | 5 | , | 1 | 5 |
| 1 | , | 9 | 6 |
The solution is: 1,96
