Solution - Long subtraction
2.403
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | . | 3 | 5 | 7 | |
| - | 1 | 2 | . | 9 | 5 | 4 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
7-4=3
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | . | 3 | 5 | 7 | |
| - | 1 | 2 | . | 9 | 5 | 4 |
| . | 3 |
Subtract the numbers in the hundredths column from the top number:
5-5=0
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | . | 3 | 5 | 7 | |
| - | 1 | 2 | . | 9 | 5 | 4 |
| . | 0 | 3 |
Because the upper digit (3) 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 (13).
