Solution - Long subtraction
65.44
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | ||
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
4-0=4
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| . | 4 |
Because the upper digit (0) in the tenths 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 (10).
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 10 | ||||
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
10-6=4
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 10 | ||||
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| . | 4 | 4 |
Subtract the numbers in the ones column from the top number:
8-3=5
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 10 | ||||
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| 5 | . | 4 | 4 |
Write 6 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 10 | ||||
| 6 | 9 | . | 0 | 4 | |
| - | 3 | . | 6 | 0 | |
| 6 | 5 | . | 4 | 4 |
The solution is: 65.44
