Solution - Long subtraction
0.68
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (15).
| Place value | ones | . | tenths | hundredths |
| 2 | 15 | |||
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| . |
Subtract the numbers in the hundredths column from the top number:
15-7=8
| Place value | ones | . | tenths | hundredths |
| 2 | 15 | |||
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| . | 8 |
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (12).
| Place value | ones | . | tenths | hundredths |
| 0 | 12 | |||
| 2 | 15 | |||
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
12-6=6
| Place value | ones | . | tenths | hundredths |
| 0 | 12 | |||
| 2 | 15 | |||
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| . | 6 | 8 |
Subtract the numbers in the ones column from the top number:
0-0=0
| Place value | ones | . | tenths | hundredths |
| 0 | 12 | |||
| 2 | 15 | |||
| 1 | . | 3 | 5 | |
| - | 0 | . | 6 | 7 |
| 0 | . | 6 | 8 |
The solution is: 0.68
