Soluzione - Long subtraction
0,16
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 0 | , | 9 | 3 | |
| - | 0 | , | 7 | 7 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the hundredths 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 (13).
| Place value | ones | . | tenths | hundredths |
| 8 | 13 | |||
| 0 | , | 9 | 3 | |
| - | 0 | , | 7 | 7 |
| , |
Subtract the numbers in the hundredths column from the top number:
13-7=6
| Place value | ones | . | tenths | hundredths |
| 8 | 13 | |||
| 0 | , | 9 | 3 | |
| - | 0 | , | 7 | 7 |
| , | 6 |
Subtract the numbers in the tenths column from the top number:
8-7=1
| Place value | ones | . | tenths | hundredths |
| 8 | 13 | |||
| 0 | , | 9 | 3 | |
| - | 0 | , | 7 | 7 |
| , | 1 | 6 |
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | ones | . | tenths | hundredths |
| 8 | 13 | |||
| 0 | , | 9 | 3 | |
| - | 0 | , | 7 | 7 |
| 0 | , | 1 | 6 |
The solution is: 0,16
