40 minutes as a Decimal

Professor Greenline Explaining Math Concepts

Converting time into decimal is a straightforward process. To begin, it's essential to understand the concept of minutes and decimals. Minutes are a unit of time, with 60 minutes equaling one hour. A decimal is a way to represent parts of a whole using a decimal point to separate the whole number from the fractional part. In this context, we aim to convert minutes into a decimal representation of hours.

40 minutes as a decimal

 

Answer

 

40 minutes can be expressed as a decimal of an hour as 0.6667. This is a terminating decimal, which means it ends after a finite number of digits.

 

Explanation

 

To convert 40 minutes into a decimal of an hour, we use division. Since there are 60 minutes in an hour, we divide 40 by 60.

 

Step 1: Identify the number of minutes (40) and the total number of minutes in an hour (60).

 

Step 2: Divide 40 by 60 to get the decimal form.

 

Step 3: Perform the division: 40 ÷ 60 = 0.6667. This means 40 minutes is 0.6667 of an hour.

 

The division process ends here, as we reach a terminating decimal.
