Solution - Long subtraction
17.34
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
5-1=4
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| . | 4 |
Because the upper digit (1) 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 (11).
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 11 | ||||
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
11-8=3
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 11 | ||||
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| . | 3 | 4 |
Subtract the numbers in the ones column from the top number:
8-1=7
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 11 | ||||
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| 7 | . | 3 | 4 |
Subtract the numbers in the tens column from the top number:
5-4=1
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 11 | ||||
| 5 | 9 | . | 1 | 5 | |
| - | 4 | 1 | . | 8 | 1 |
| 1 | 7 | . | 3 | 4 |
The solution is: 17.34
