Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 5 | , | 0 | 3 | |
| - | 3 | 1 | , | 7 | |
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 5 | , | 0 | 3 | |
| - | 3 | 1 | , | 7 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
3-0=3
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 5 | , | 0 | 3 | |
| - | 3 | 1 | , | 7 | 0 |
| , | 3 |
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (10).

| , | 3 |
Subtract the numbers in the tenths column from the top number:
10-7=3
| Place value | tens | ones | . | tenths | hundredths |

Subtract the numbers in the ones column from the top number:
4-1=3
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 10 | ||||
| 4 | 5 | , | 0 | 3 | |
| - | 3 | 1 | , | 7 | 0 |
| 3 | , | 3 | 3 |
Subtract the numbers in the tens column from the top number:
4-3=1
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 10 | ||||
| 4 | 5 | , | 0 | 3 | |
| - | 3 | 1 | , | 7 | 0 |
| 1 | 3 | , | 3 | 3 |
The solution is: 13,33
