Solution - Long subtraction
35.74
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
7-3=4
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| . | 4 |
Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 11 | ||||
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| . | 4 |
Subtract the numbers in the tenths column from the top number:
11-4=7
| Place value | tens | ones | . | tenths | hundredths |
| 1 | 11 | ||||
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| . | 7 | 4 |
Because the upper digit (1) in the ones column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (11).
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 11 | ||||
| 1 | 11 | ||||
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| . | 7 | 4 |
Subtract the numbers in the ones column from the top number:
11-6=5
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 11 | ||||
| 1 | 11 | ||||
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| 5 | . | 7 | 4 |
Write 3 in the tens place.
| Place value | tens | ones | . | tenths | hundredths |
| 3 | 11 | ||||
| 1 | 11 | ||||
| 4 | 2 | . | 1 | 7 | |
| - | 6 | . | 4 | 3 | |
| 3 | 5 | . | 7 | 4 |
The solution is: 35.74
