Solution - Long subtraction
14.05
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| . |
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 number to the left (2.0) which becomes (1.9) and get (13).
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| . |
Subtract the numbers in the hundredths column from the top number:
13-8=5
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| . | 5 |
Subtract the numbers in the tenths column from the top number:
9-9=0
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| . | 0 | 5 |
Because the upper digit (1) in the ones 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 | tens | ones | . | tenths | hundredths |
| 5 | 11 | ||||
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| . | 0 | 5 |
Subtract the numbers in the ones column from the top number:
11-7=4
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 11 | ||||
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| 4 | . | 0 | 5 |
Subtract the numbers in the tens column from the top number:
5-4=1
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 11 | ||||
| 1 | 9 | 13 | |||
| 6 | 2 | . | 0 | 3 | |
| - | 4 | 7 | . | 9 | 8 |
| 1 | 4 | . | 0 | 5 |
The solution is: 14.05
