Solution - Long subtraction
100.48
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (3.0) which becomes (2.9) and get (14).
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| . |
Subtract the numbers in the hundredths column from the top number:
14-6=8
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
9-5=4
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| . | 4 | 8 |
Subtract the numbers in the ones column from the top number:
2-2=0
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| 0 | . | 4 | 8 |
Subtract the numbers in the tens column from the top number:
1-1=0
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| 0 | 0 | . | 4 | 8 |
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 9 | 14 | ||||
| 1 | 1 | 3 | . | 0 | 4 | |
| - | 1 | 2 | . | 5 | 6 | |
| 1 | 0 | 0 | . | 4 | 8 |
The solution is: 100.48
