Solution - Long subtraction
1.12
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
9-7=2
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| . | 2 |
Subtract the numbers in the tenths column from the top number:
5-4=1
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| . | 1 | 2 |
Because the upper digit (0) in the ones 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 (10).
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| . | 1 | 2 |
Subtract the numbers in the ones column from the top number:
10-9=1
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| 1 | . | 1 | 2 |
Write 0 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 10 | ||||
| 1 | 0 | . | 5 | 9 | |
| - | 9 | . | 4 | 7 | |
| 0 | 1 | . | 1 | 2 |
The solution is: 1.12
