50.0465
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 7 | . | 0 | 9 | |||
| - | 7 | . | 0 | 4 | 3 | 5 | |
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 5 | 7 | . | 0 | 9 | 0 | 0 | |
| - | 7 | . | 0 | 4 | 3 | 5 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (90) which becomes (89) and get (10).
