20 minutes as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on decimal conversion. Firstly, we need to understand time and decimal representation. Time can be expressed in hours, minutes, and seconds. There are 60 minutes in an hour, so when converting minutes to a decimal, we are finding what fraction of an hour those minutes represent. A decimal is a way to express a number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

Step 1: Identify the number of minutes and the total minutes in an hour. Here, 20 is the number of minutes, and 60 is the total minutes in an hour.

 

Step 2: Divide 20 by 60 to find the decimal representation.

 

Step 3: Simplify the fraction 20/60, which reduces to 1/3.

 

Step 4: Divide 1 by 3 to get the decimal, which is 0.3333.

 

This process shows that 20 minutes is 0.3333 hours.
