9 hours and 45 minutes as a decimal

Professor Greenline Explaining Math Concepts

This is a simple question on converting time to decimal form. To perform this conversion, we must understand how to express hours and minutes as decimal values. Time is typically measured in hours and minutes, but decimals allow us to represent this time in a different format, which can be useful for various calculations. In a decimal format, the whole part represents the full hours, and the decimal part represents the minutes as a fraction of an hour.
