Solution - Long subtraction
447.69
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | ||||
| . |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
9-0=9
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| . | 9 |
Subtract the numbers in the tenths column from the top number:
6-0=6
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| . | 6 | 9 |
Because the upper digit (6) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (50) which becomes (49) and get (16).
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 16 | ||||
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| . | 6 | 9 |
Subtract the numbers in the ones column from the top number:
16-9=7
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 16 | ||||
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| 7 | . | 6 | 9 |
Subtract the numbers in the tens column from the top number:
9-5=4
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 16 | ||||
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| 4 | 7 | . | 6 | 9 |
Write 4 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 16 | ||||
| 5 | 0 | 6 | . | 6 | 9 | |
| - | 5 | 9 | . | 0 | 0 | |
| 4 | 4 | 7 | . | 6 | 9 |
The solution is: 447.69
