Soluzione - Long subtraction
47,3
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 7 | 4 | , | 5 | |
| - | 2 | 7 | , | 2 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the tenths column from the top number:
5-2=3
| Place value | tens | ones | . | tenths |
| 7 | 4 | , | 5 | |
| - | 2 | 7 | , | 2 |
| , | 3 |
Because the upper digit (4) in the ones 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 (14).
| Place value | tens | ones | . | tenths |
| 6 | 14 | |||
| 7 | 4 | , | 5 | |
| - | 2 | 7 | , | 2 |
| , | 3 |
Subtract the numbers in the ones column from the top number:
14-7=7
| Place value | tens | ones | . | tenths |
| 6 | 14 | |||
| 7 | 4 | , | 5 | |
| - | 2 | 7 | , | 2 |
| 7 | , | 3 |
Subtract the numbers in the tens column from the top number:
6-2=4
| Place value | tens | ones | . | tenths |
| 6 | 14 | |||
| 7 | 4 | , | 5 | |
| - | 2 | 7 | , | 2 |
| 4 | 7 | , | 3 |
The solution is: 47,3
