Solution - Long subtraction
4.766
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths |
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | ||
| . |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths |
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
6-0=6
| Place value | ones | . | tenths | hundredths | thousandths |
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| . | 6 |
Subtract the numbers in the hundredths column from the top number:
6-0=6
| Place value | ones | . | tenths | hundredths | thousandths |
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| . | 6 | 6 |
Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (11).
| Place value | ones | . | tenths | hundredths | thousandths |
| 4 | 11 | ||||
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| . | 6 | 6 |
Subtract the numbers in the tenths column from the top number:
11-4=7
| Place value | ones | . | tenths | hundredths | thousandths |
| 4 | 11 | ||||
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| . | 7 | 6 | 6 |
Subtract the numbers in the ones column from the top number:
4-0=4
| Place value | ones | . | tenths | hundredths | thousandths |
| 4 | 11 | ||||
| 5 | . | 1 | 6 | 6 | |
| - | 0 | . | 4 | 0 | 0 |
| 4 | . | 7 | 6 | 6 |
The solution is: 4.766
