Soluzione - Long subtraction
2,34
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | |
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths |
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
4-0=4
| Place value | ones | . | tenths | hundredths |
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | 0 |
| , | 4 |
Because the upper digit (0) in the tenths 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 (10).
| Place value | ones | . | tenths | hundredths |
| 8 | 10 | |||
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | 0 |
| , | 4 |
Subtract the numbers in the tenths column from the top number:
10-7=3
| Place value | ones | . | tenths | hundredths |
| 8 | 10 | |||
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | 0 |
| , | 3 | 4 |
Subtract the numbers in the ones column from the top number:
8-6=2
| Place value | ones | . | tenths | hundredths |
| 8 | 10 | |||
| 9 | , | 0 | 4 | |
| - | 6 | , | 7 | 0 |
| 2 | , | 3 | 4 |
The solution is: 2,34
