Solution - Long subtraction
436.87
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 4 | 7 | ||||
| - | 1 | 0 | . | 1 | 3 | |
| . |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| . |
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 (7.0) which becomes (6.9) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| . |
Subtract the numbers in the hundredths column from the top number:
10-0-3=7
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| . | 7 |
Subtract the numbers in the tenths column from the top number:
9-1=8
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| . | 8 | 7 |
Subtract the numbers in the ones column from the top number:
6-0=6
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| 6 | . | 8 | 7 |
Subtract the numbers in the tens column from the top number:
4-1=3
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| 3 | 6 | . | 8 | 7 |
Write 4 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 4 | 4 | 7 | . | 0 | 0 | |
| - | 1 | 0 | . | 1 | 3 | |
| 4 | 3 | 6 | . | 8 | 7 |
The solution is: 436.87
