Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (3) 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 (13).
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . |
Subtract the numbers in the hundredths column from the top number:
13-7=6
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . | 6 |
Because the upper digit (5) in the tenths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (15).
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 15 | ||||
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . | 6 |
Subtract the numbers in the tenths column from the top number:
15-8=7
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 15 | ||||
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . | 7 | 6 |
Because the upper digit (4) in the ones column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (14).
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 14 | ||||
| 4 | 15 | ||||
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| . | 7 | 6 |
Subtract the numbers in the ones column from the top number:
14-8=6
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 14 | ||||
| 4 | 15 | ||||
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| 6 | . | 7 | 6 |
Subtract the numbers in the tens column from the top number:
2-1=1
| Place value | tens | ones | . | tenths | hundredths |
| 2 | 14 | ||||
| 4 | 15 | ||||
| 5 | 13 | ||||
| 3 | 5 | . | 6 | 3 | |
| - | 1 | 8 | . | 8 | 7 |
| 1 | 6 | . | 7 | 6 |
The solution is: 16.76
