In the realm of mathematics, percentages play a pivotal role in quantifying parts of a whole. They are ubiquitous in everyday life, from calculating discounts at the grocery store to determining the proportion of votes in an election. Understanding how to calculate percentages is essential for navigating the world around us effectively. One common scenario involves determining what percentage one number represents of another. For instance, “24 is what percent of 75?” This seemingly simple question can unlock a deeper understanding of percentage calculations and their practical applications.
This blog post delves into the intricacies of calculating percentages, specifically addressing the question “24 is what percent of 75?” We will explore the underlying concepts, step-by-step solutions, and real-world examples to illuminate the significance of this calculation. By the end of this post, you will not only know the answer to the question but also gain a comprehensive grasp of percentage calculations and their relevance in various contexts.
Understanding Percentages
A percentage is a fraction expressed as a number out of one hundred. The symbol “%” represents “out of one hundred.” For example, 50% is equivalent to 50/100, which simplifies to 1/2. Percentages are used to represent proportions, parts of a whole, and rates of change.
Calculating Percentages
To calculate a percentage, follow these steps:
- Divide the part by the whole. This gives you a decimal representation of the proportion.
- Multiply the decimal by 100 to express the proportion as a percentage.
For instance, to find what percentage 24 is of 75, we would divide 24 by 75 and then multiply the result by 100.
Solving the Problem: 24 is What Percent of 75?
Let’s break down the calculation step-by-step:
1. **Divide the part (24) by the whole (75):** 24 / 75 = 0.32 (See Also: How Much Percent Is Sleep Apnea Va Disability? Claiming Your Benefits)
