18 minutes as a decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn about time and decimals. Time can be represented in different forms, including hours and minutes. 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. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

Answer

18 minutes as a decimal of an hour can be written as 0.3.

 

Explanation

 

To convert 18 minutes to a decimal, we will use the conversion of minutes to hours. There are 60 minutes in an hour. Thus, to find the decimal representation of 18 minutes, we divide 18 by 60. Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the total minutes (18) which will be divided by the number of minutes in an hour (60).

 

Step 2: Perform the division: 18 ÷ 60 = 0.3.

 

Step 3: The quotient, 0.3, is the decimal representation of 18 minutes as a part of an hour.

 

This process gives us the decimal representation of 18 minutes as 0.3.
