247.84
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 5 | 0 | . | 2 | 6 | |
| - | 2 | . | 4 | 2 | ||
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
6-2=4
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 5 | 0 | . | 2 | 6 | |
| - | 2 | . | 4 | 2 | ||
| . | 4 |
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the number to the left (50) which becomes (49) and get (12).
