3,75
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 6 | ||||
| - | 2 | , | 2 | 5 |
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths |
| 6 | , | 0 | 0 | |
| - | 2 | , | 2 | 5 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (6.0) which becomes (5.9) and get (10).
| Place value | ones | . | tenths | hundredths |
| 5 | 9 | 10 | ||
| 6 | , | 0 | 0 | |
| - | 2 | , | 2 | 5 |
| , |
Subtract the numbers in the hundredths column from the top number:
10-0-5=5
| Place value | ones | . | tenths | hundredths |
| 5 | 9 | 10 | ||
| 6 | , | 0 | 0 | |
| - | 2 | , | 2 | 5 |
| , | 5 |
Subtract the numbers in the tenths column from the top number:
9-2=7
| Place value | ones | . | tenths | hundredths |
| 5 | 9 | 10 | ||
| 6 | , | 0 | 0 | |
| - | 2 | , | 2 | 5 |
| , | 7 | 5 |
Subtract the numbers in the ones column from the top number:
5-2=3
| Place value | ones | . | tenths | hundredths |
| 5 | 9 | 10 | ||
| 6 | , | 0 | 0 | |
| - | 2 | , | 2 | 5 |
| 3 | , | 7 | 5 |
The solution is: 3,75
