Unlock the Secret: How to Find 54% of 80 – A Percentage Calculation Tutorial

Finding a percentage of a number is a fundamental skill with wide-ranging applications, from calculating discounts and taxes to understanding statistics and data analysis. This tutorial will walk you through a step-by-step process of calculating 54% of 80, explaining the underlying principles so you can confidently tackle any percentage problem. Mastering percentage calculations opens doors to numerous practical applications in everyday life and professional settings.

Understanding the Basics: Percentage Calculation Methods

Before diving into the specific calculation of 54% of 80, let's refresh our understanding of percentages. A percentage represents a fraction of 100. For example, 54% can be written as 54/100 or 0.54. There are two primary methods for calculating percentages:

• Method 1: Using Decimal Conversion: Convert the percentage to a decimal and multiply it by the number. This is the most straightforward approach.

• Method 2: Using Fractions: Convert the percentage to a fraction and multiply it by the number. This method is helpful for understanding the underlying mathematical principles.

Calculating 54% of 80: A Step-by-Step Guide

Let's apply these methods to calculate 54% of 80.

Method 1: Decimal Conversion

1. Convert the percentage to a decimal: 54% = 54/100 = 0.54

2. Multiply the decimal by the number: 0.54 * 80 = 43.2

Therefore, 54% of 80 is $\boxed{43.2}$

Method 2: Fraction Conversion

1. Convert the percentage to a fraction: 54% = 54/100

2. Simplify the fraction (if possible): 54/100 can be simplified to 27/50

3. Multiply the fraction by the number: (27/50) * 80 = (27 * 80) / 50 = 2160 / 50 = 43.2

Again, we find that 54% of 80 is $\boxed{43.2}$
