20 is What Percent of 160? A Simple Percentage Calculation Explained

Finding out what percentage 20 represents of 160 is a common mathematical problem with applications in various fields, from calculating discounts to understanding data proportions. This article will guide you through the calculation, explaining the process step-by-step and offering helpful tips for solving similar percentage problems. Understanding this fundamental concept is crucial for anyone working with data analysis, budgeting, or simply navigating everyday percentage-based scenarios.

Understanding the Problem

The question "20 is what percent of 160?" asks us to determine the ratio of 20 to 160 and express this ratio as a percentage. A percentage is simply a fraction expressed as parts per hundred. We need to find the fraction 20/160 and convert it into a percentage.

Step-by-Step Calculation

Here's how to calculate what percentage 20 is of 160:

1. Set up the equation: We can represent the problem as an equation:

   x% * 160 = 20

   Where 'x' represents the percentage we need to find.

2. Solve for x: To isolate 'x', we divide both sides of the equation by 160:

   x% = 20 / 160

3. Simplify the fraction: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 20:

   x% = 1 / 8

4. Convert to a decimal: Convert the fraction to a decimal by dividing the numerator by the denominator:

   x% = 0.125

5. Convert to a percentage: Multiply the decimal by 100 to express it as a percentage:

   x% = 0.125 * 100 = 12.5%

Therefore, 20 is 12.5% of 160.

Alternative Method: Using Proportions

Another approach involves setting up a proportion:

20/160 = x/100

Cross-multiplying gives:

160x = 2000

Dividing both sides by 160:

x = 12.5

Therefore, x = 12.5%, confirming our previous result.
