Solution - Long subtraction
4.74
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths |
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
7-7=0
| Place value | ones | . | tenths | hundredths | thousandths |
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| . | 0 |
Because the upper digit (1) in the hundredths 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 | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| . | 0 |
Subtract the numbers in the hundredths column from the top number:
11-7=4
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| . | 4 | 0 |
Subtract the numbers in the tenths column from the top number:
8-1=7
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| . | 7 | 4 | 0 |
Subtract the numbers in the ones column from the top number:
4-0=4
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 4 | . | 9 | 1 | 7 | |
| - | 0 | . | 1 | 7 | 7 |
| 4 | . | 7 | 4 | 0 |
The solution is: 4.74
