Solution - Long subtraction
272.6494
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 2 | 8 | 5 | . | 7 | 5 | |||
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (50) which becomes (49) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . |
Subtract the numbers in the ten thousandths column from the top number:
10-0-6=4

| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . | 4 |
Subtract the numbers in the thousandths column from the top number:
9-0=9
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . | 9 | 4 |
Subtract the numbers in the hundredths column from the top number:
4-0=4
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . | 4 | 9 | 4 |
Subtract the numbers in the tenths column from the top number:
7-1=6
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| . | 6 | 4 | 9 | 4 |
Subtract the numbers in the ones column from the top number:
5-3=2
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| 2 | . | 6 | 4 | 9 | 4 |
Subtract the numbers in the tens column from the top number:
8-1=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| 7 | 2 | . | 6 | 4 | 9 | 4 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 4 | 9 | 10 | ||||||
| 2 | 8 | 5 | . | 7 | 5 | 0 | 0 | |
| - | 1 | 3 | . | 1 | 0 | 0 | 6 | |
| 2 | 7 | 2 | . | 6 | 4 | 9 | 4 |
The solution is: 272.6494
