653%
- C.

- D.
6.53%
Correct Answer
A. .653Explanation
To divide 65.3 by 100, you simply move the decimal point two places to the left. This is because when you divide by 100, you are essentially dividing by 10 twice, which means you need to decrease the value by two decimal places.
So, starting with 65.3, you move the decimal point two places to the left to get 0.653. This is the result of dividing 65.3 by 100.Rate this question:
