Solution - Long subtraction
41.14
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the hundredths 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 | tens | ones | . | tenths | hundredths |
| 8 | 12 | ||||
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| . |
Subtract the numbers in the hundredths column from the top number:
12-8=4
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 12 | ||||
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
8-7=1
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 12 | ||||
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| . | 1 | 4 |
Subtract the numbers in the ones column from the top number:
9-8=1
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 12 | ||||
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| 1 | . | 1 | 4 |
Write 4 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 12 | ||||
| 4 | 9 | . | 9 | 2 | |
| - | 8 | . | 7 | 8 | |
| 4 | 1 | . | 1 | 4 |
The solution is: 41.14
