Solution - Long subtraction
25.34
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | ||
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
4-0=4
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| . | 4 |
Because the upper digit (0) in the tenths 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 (10).
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 10 | ||||
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
10-7=3
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 10 | ||||
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| . | 3 | 4 |
Subtract the numbers in the ones column from the top number:
6-1=5
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 10 | ||||
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| 5 | . | 3 | 4 |
Write 2 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 10 | ||||
| 2 | 7 | . | 0 | 4 | |
| - | 1 | . | 7 | 0 | |
| 2 | 5 | . | 3 | 4 |
The solution is: 25.34
