90 minutes as a Decimal

Professor Greenline Explaining Math Concepts

Understanding how to convert time to decimals is a simple yet important skill. Time is often measured in hours, minutes, and seconds. In some contexts, such as calculations for payroll or project management, it's useful to express time as a decimal. Here, we'll focus on converting 90 minutes into a decimal format. A decimal separates the whole number part from the fraction part using a decimal point. The numbers to the left of the decimal point represent the whole hour, and those to the right represent the fractional part of the hour.

Answer

90 minutes as a decimal is 1.5. This indicates that 90 minutes is equivalent to 1 and a half hours.

 

Explanation

To convert 90 minutes to a decimal, we divide the number of minutes by 60, since there are 60 minutes in an hour. Here's the step-by-step breakdown of the process:

 

Step 1: Identify the total minutes, which is 90 in this case.

 

Step 2: Divide the total minutes by 60 to convert minutes into hours.

 

Step 3: 90 ÷ 60 = 1.5 Step 4: The result, 1.5, represents 1 whole hour and 0.5 of another hour.

 

Thus, 90 minutes is equal to 1.5 hours in decimal form.
