Soluzione - Long subtraction
3,04
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 4 | , | 7 | 2 | |
| - | 1 | , | 6 | 8 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the hundredths 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 (12).
| Place value | ones | . | tenths | hundredths |
| 6 | 12 | |||
| 4 | , | 7 | 2 | |
| - | 1 | , | 6 | 8 |
| , |
Subtract the numbers in the hundredths column from the top number:
12-8=4
| Place value | ones | . | tenths | hundredths |
| 6 | 12 | |||
| 4 | , | 7 | 2 | |
| - | 1 | , | 6 | 8 |
| , | 4 |
Subtract the numbers in the tenths column from the top number:
6-6=0
| Place value | ones | . | tenths | hundredths |
| 6 | 12 | |||
| 4 | , | 7 | 2 | |
| - | 1 | , | 6 | 8 |
| , | 0 | 4 |
Subtract the numbers in the ones column from the top number:
4-1=3
| Place value | ones | . | tenths | hundredths |
| 6 | 12 | |||
| 4 | , | 7 | 2 | |
| - | 1 | , | 6 | 8 |
| 3 | , | 0 | 4 |
The solution is: 3,04
