What Percentage is 170 out of 200? A Simple Guide to Percentage Calculations

Calculating percentages is a fundamental skill with applications across various fields, from academic assignments to financial planning. This article will clearly explain how to determine what percentage 170 represents out of 200, and provide you with the tools to solve similar problems efficiently. Understanding this process will significantly improve your numerical literacy and problem-solving abilities.

Understanding Percentages:

A percentage is a fraction of 100. It expresses a proportion or rate per 100. The symbol % denotes percentage. For instance, 50% signifies 50 out of 100, or one-half.

Calculating the Percentage:

To find what percentage 170 represents out of 200, we'll use the following formula:

(Part / Whole) * 100% = Percentage

In this case:

• Part: 170
• Whole: 200

Let's plug the values into the formula:

(170 / 200) * 100% = 85%

Therefore, 170 out of 200 is 85%.

Step-by-Step Breakdown:
