Solution - Long subtraction
26.88
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | tens | ones | . | tenths | hundredths |
4 | 8 | . | 4 | 5 | |
- | 2 | 1 | . | 5 | 7 |
. |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (15).
Place value | tens | ones | . | tenths | hundredths |
3 | 15 | ||||
4 | 8 | . | 4 | 5 | |
- | 2 | 1 | . | 5 | 7 |
. |
Subtract the numbers in the hundredths column from the top number:
15-7=8
Place value | tens | ones | . | tenths | hundredths |

4 | 8 | . | 4 | 5 | |
- | 2 | 1 | . | 5 | 7 |
. | 8 |
Because the upper digit (3) in the tenths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (13).

Subtract the numbers in the tenths column from the top number:
13-5=8

Subtract the numbers in the ones column from the top number:
7-1=6

Subtract the numbers in the tens column from the top number:
4-2=2
Place value | tens | ones | . | tenths | hundredths |
7 | 13 | ||||
3 | 15 | ||||
4 | 8 | . | 4 | 5 | |
- | 2 | 1 | . | 5 | 7 |
2 | 6 | . | 8 | 8 |
The solution is: 26.88
