50% as a decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn percentages and decimals. A percentage represents a part of a whole out of 100. In this case, 50% represents 50 parts out of 100. A decimal is a way to represent a number that is not whole, using a (.) or 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.

50 percent as a decimalAnswer

 

50% in decimal form can be written as 0.5. It is a terminating decimal, meaning it does not repeat infinitely.

 

Explanation

 

To convert 50% to a decimal, we will use the division method. Since a percentage is a fraction out of 100, 50% is equivalent to 50/100. Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the percentage and recognize it as a fraction out of 100. Here, 50% is the same as 50/100.

 

Step 2: Simplify the fraction 50/100 by dividing both the numerator (50) and the denominator (100) by their greatest common divisor, which is 50. This gives us 1/2.

 

Step 3: Convert the fraction 1/2 to a decimal by dividing the numerator by the denominator.

 

Step 4: 1 divided by 2 equals 0.5.

 

The answer for 50% as a decimal will be 0.5.
