Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (3.0) which becomes (2.9) and get (11).
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 9 | 11 | |||
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| , |
Subtract the numbers in the hundredths column from the top number:
11-4=7
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 9 | 11 | |||
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| , | 7 |
Subtract the numbers in the tenths column from the top number:
9-0=9
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 9 | 11 | |||
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| , | 9 | 7 |
Subtract the numbers in the ones column from the top number:
2-0=2
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 9 | 11 | |||
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| 2 | , | 9 | 7 |
Write 2 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 9 | 11 | |||
| 2 | 3 | , | 0 | 1 | |
| - | 0 | , | 0 | 4 | |
| 2 | 2 | , | 9 | 7 |
The solution is: 22,97
