Answer:
The answer is 231.56.
Explanation:
To solve this problem, we can use the following steps:
Align the numbers by their decimal points and write them one below the other.
Add zeros to the right of the decimal point if needed to make the numbers have the same number of digits after the decimal point.
Subtract each pair of digits starting from the rightmost column and write the result below the line. If the top digit is smaller than the bottom digit, borrow 1 from the next column to the left and add 10 to the top digit.
Write a decimal point in the answer directly below the decimal points in the numbers.
Simplify the answer if possible by removing any trailing zeros after the decimal point.
Using these steps, we can solve the problem as follows:
543.73
- 312.17
