Solution - Long subtraction
1.58
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths |
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (13).
| Place value | ones | . | tenths | hundredths |
| 1 | 13 | |||
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| . |
Subtract the numbers in the hundredths column from the top number:
13-5=8
| Place value | ones | . | tenths | hundredths |
| 1 | 13 | |||
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| . | 8 |
Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (11).
| Place value | ones | . | tenths | hundredths |
| 5 | 11 | |||
| 1 | 13 | |||
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
11-6=5
| Place value | ones | . | tenths | hundredths |
| 5 | 11 | |||
| 1 | 13 | |||
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| . | 5 | 8 |
Subtract the numbers in the ones column from the top number:
5-4=1
| Place value | ones | . | tenths | hundredths |
| 5 | 11 | |||
| 1 | 13 | |||
| 6 | . | 2 | 3 | |
| - | 4 | . | 6 | 5 |
| 1 | . | 5 | 8 |
The solution is: 1.58
