$Write the percentage as a fraction$

Introduction

When dealing with percentages, it's often necessary to convert them into their equivalent fractions. This can be particularly useful in various mathematical operations, such as adding or subtracting percentages, or when working with ratios and proportions. In this article, we will explore the process of converting 66% into its equivalent fraction in simplest form.

Understanding Percentages and Fractions

To begin, let's clarify the concept of percentages and fractions. A percentage is a way of expressing a value as a fraction of 100. For example, 66% can be read as "66 out of 100." On the other hand, a fraction is a way of expressing a part of a whole as a ratio of two numbers. In the case of 66%, the fraction equivalent would be 66/100.

Converting 66% to a Fraction

To convert 66% to a fraction, we can use the following steps:

Write the percentage as a fraction: We start by writing 66% as a fraction, which is 66/100.
Simplify the fraction: To simplify the fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator. In this case, the GCD of 66 and 100 is 2.
Divide both the numerator and the denominator by the GCD: By dividing both the numerator and the denominator by 2, we get 33/50.

Explaining the Simplification Process

Let's break down the simplification process step by step:

Step 1: Find the GCD: To find the GCD of 66 and 100, we can list the factors of each number. The factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. By comparing the lists, we can see that the greatest common factor is 2.
Step 2: Divide both the numerator and the denominator by the GCD: By dividing both the numerator and the denominator by 2, we get 33/50.

Conclusion

In conclusion, the fraction equivalent of 66% in simplest form is 33/50. This can be verified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Understanding how to convert percentages to fractions is an essential skill in mathematics, and it can be applied to a wide range of problems and applications.
