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.
