Solution - Long subtraction
62.88
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | |
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
8-0=8
| Place value | tens | ones | . | tenths | hundredths |
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| . | 8 |
Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (11).
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 11 | ||||
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| . | 8 |
Subtract the numbers in the tenths column from the top number:
11-3=8
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 11 | ||||
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| . | 8 | 8 |
Subtract the numbers in the ones column from the top number:
7-5=2
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 11 | ||||
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| 2 | . | 8 | 8 |
Subtract the numbers in the tens column from the top number:
9-3=6
| Place value | tens | ones | . | tenths | hundredths |
| 7 | 11 | ||||
| 9 | 8 | . | 1 | 8 | |
| - | 3 | 5 | . | 3 | 0 |
| 6 | 2 | . | 8 | 8 |
The solution is: 62.88
