Solution - Long subtraction
14.92
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | ||
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
2-0=2
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| . | 2 |
Because the upper digit (5) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (15).
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 15 | ||||
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| . | 2 |
Subtract the numbers in the tenths column from the top number:
15-6=9
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 15 | ||||
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| . | 9 | 2 |
Because the upper digit (3) in the ones 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 | tens | ones | . | tenths | hundredths |
| 1 | 13 | ||||
| 3 | 15 | ||||
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| . | 9 | 2 |
Subtract the numbers in the ones column from the top number:
13-9=4
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 13 | ||||
| 3 | 15 | ||||
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| 4 | . | 9 | 2 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 13 | ||||
| 3 | 15 | ||||
| 2 | 4 | . | 5 | 2 | |
| - | 9 | . | 6 | 0 | |
| 1 | 4 | . | 9 | 2 |
The solution is: 14.92
