Understanding Percentages: A Comprehensive Exploration of Finding What Percent One Number Is of Another

Percentages are a fundamental concept in mathematics and play a significant role in everyday life, from calculating discounts during a sale to understanding statistics and data in various fields. In this comprehensive blog post, we will delve into the process of finding what percent one number is of another, specifically addressing the question: What percent of 25 is 30?

Understanding Percentages:

A percentage is a way to express a fraction of a whole, with 100 equal parts as the standard reference. The term “percent” literally means “per hundred,” denoted by the symbol “%.” Therefore, when we say “percent,” we’re referring to a value out of 100.

Step 1: Identify the Numbers:

In the question, “What percent of 25 is 30?” we have two numbers:

1. The whole or the base number: 25
2. The part or the number we want to find the percentage of: 30

Step 2: Set Up the Percentage Equation:

To find the percentage, we can set up a proportion:

PartWhole=3025WholePart​=2530​

Now, let’s proceed to solve for the percentage.

Step 3: Simplify the Fraction:
