Solution - Long subtraction
38.48
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (7) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (17).
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| . |
Subtract the numbers in the hundredths column from the top number:
17-9=8
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
5-1=4
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| . | 4 | 8 |
Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (13).
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 13 | ||||
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| . | 4 | 8 |
Subtract the numbers in the ones column from the top number:
13-5=8
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 13 | ||||
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| 8 | . | 4 | 8 |
Write 3 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 13 | ||||
| 5 | 17 | ||||
| 4 | 3 | . | 6 | 7 | |
| - | 5 | . | 1 | 9 | |
| 3 | 8 | . | 4 | 8 |
The solution is: 38.48
