6,75
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ones | . | tenths | hundredths |
9 | , | 2 | 5 | |
- | 2 | , | 5 | |
, |
Put zeros in the blank number places:
Place value | ones | . | tenths | hundredths |
9 | , | 2 | 5 | |
- | 2 | , | 5 | 0 |
, |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
5-0=5
Place value | ones | . | tenths | hundredths |
9 | , | 2 | 5 | |
- | 2 | , | 5 | 0 |
, | 5 |
Because the upper digit (2) 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 (12).
Place value | ones | . | tenths | hundredths |
8 | 12 | |||
9 | , | 2 | 5 | |
- | 2 | , | 5 | 0 |
, | 5 |
Subtract the numbers in the tenths column from the top number:
12-5=7
Place value | ones | . | tenths | hundredths |
8 | 12 | |||
9 | , | 2 | 5 | |
- | 2 | , | 5 | 0 |
, | 7 | 5 |
Subtract the numbers in the ones column from the top number:
8-2=6
Place value | ones | . | tenths | hundredths |
8 | 12 | |||
9 | , | 2 | 5 | |
- | 2 | , | 5 | 0 |
6 | , | 7 | 5 |
The solution is: 6,75
