14231.25
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 8 | 9 | 7 | 5 | ||||
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| . |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (5.0) which becomes (4.9) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| . |
Subtract the numbers in the hundredths column from the top number:
10-0-5=5
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| . | 5 |
Subtract the numbers in the tenths column from the top number:
9-7=2
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| . | 2 | 5 |
Subtract the numbers in the ones column from the top number:
4-3=1
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| 1 | . | 2 | 5 |
Subtract the numbers in the tens column from the top number:
7-4=3
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| 3 | 1 | . | 2 | 5 |
Subtract the numbers in the hundreds column from the top number:
9-7=2
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| 2 | 3 | 1 | . | 2 | 5 |
Subtract the numbers in the thousands column from the top number:
8-4=4
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| 4 | 2 | 3 | 1 | . | 2 | 5 |
Write 1 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 9 | 10 | ||||||
| 1 | 8 | 9 | 7 | 5 | . | 0 | 0 | |
| - | 4 | 7 | 4 | 3 | . | 7 | 5 | |
| 1 | 4 | 2 | 3 | 1 | . | 2 | 5 |
The solution is: 14231.25
