Professor Greenline Explaining Math Concepts

Numbers can be categorized into different types. Fraction is one of its kinds. It is always represented in the form of p/q, where p is the numerator and q is the denominator. A fraction represents a whole and a fractional part. Percentages represent a part of a whole as a fraction of 100. For example, 1/2 can be expressed as 50%.

What is 4.5% as a Fraction?

4.5% as a fraction

Answer

 

The answer for 4.5% as a fraction is 9/200.

 

Explanation

 

Converting a percentage to a fraction is a task for students that can be done easily. You can follow the steps mentioned below to find the answer.

 

Step 1: Firstly, any percentage should be converted to a fraction for easy calculation. Here, 4.5% is the percentage which means 4.5 out of 100. Thus, 4.5% becomes 4.5/100.

 

Step 2: To remove the decimal from a fraction, you need to multiply both the numerator and denominator by 10 (because there is only 1 decimal place). 4.5/100 × 10/10 = 45/1000

 

Step 3: Here, 5 is the GCD of 45 and 1000. Now, to make the fraction simpler, divide the numerator and denominator by 5. 45/1000 = 9/200 Hence, 4.5% is in the fraction form of 9/200.

 

Thus, 4.5% can be written as a fraction 9/200.
