20 seconds as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on converting time to a decimal format. To begin, we must understand the relationship between seconds and minutes. There are 60 seconds in one minute. A decimal is a way to represent numbers that are not whole, using a decimal point (.) to separate the whole part from the fractional part. In this context, the numbers to the left of the decimal point represent whole minutes, and those to the right represent the fractional part of the minute.

Answer

Explanation

 

To express 20 seconds as a decimal of a minute, we convert the fraction of the minute represented by 20 seconds. Here's a step-by-step breakdown of the process:

 

Step 1: Recognize that there are 60 seconds in a minute. The fraction of the minute that 20 seconds represents is 20/60.

 

Step 2: Simplify the fraction 20/60, which equals 1/3.

 

Step 3: To convert 1/3 into a decimal, we use division.

 

Step 4: 1 divided by 3 gives 0.3333...

 

Step 5: This process results in a recurring decimal, as the remainder does not become zero.

 

Thus, 20 seconds as a decimal of a minute is 0.3333...
