Fraction Percent Decimal Worksheet: Master Conversion Skills
Table of Contents :
Understanding how to convert fractions, percentages, and decimals is a fundamental math skill that plays a crucial role in various aspects of life, including finance, measurement, and even cooking! In this article, we will delve into the key concepts surrounding these three number forms, how they interrelate, and provide a comprehensive worksheet designed to help you master these essential conversion skills.
What Are Fractions, Percentages, and Decimals? 📊
Before we tackle conversions, it’s important to understand what fractions, percentages, and decimals are individually.
Fractions
A fraction consists of two numbers: a numerator (the top number) and a denominator (the bottom number). It represents a part of a whole. For example, in the fraction ( \frac{3}{4} ), 3 is the numerator, and 4 is the denominator, indicating that we are looking at three parts of a whole divided into four equal parts.
Percentages
A percentage is a special type of fraction that is based on 100. The symbol “%” denotes this. For instance, 25% can be understood as ( \frac{25}{100} ) or 25 parts out of 100.
Decimals
Decimals represent fractions in a different form, often used in mathematics and real-world scenarios for precision. For example, the decimal 0.75 represents the fraction ( \frac{75}{100} ) or 75%.
The Interconnections 🔗
Converting among fractions, decimals, and percentages is a vital skill, as they frequently appear in everyday situations. Below is a simple guide on how to convert each type.
From Fraction to Decimal
To convert a fraction to a decimal, simply divide the numerator by the denominator.
Example:
- ( \frac{3}{4} = 3 ÷ 4 = 0.75 )
From Decimal to Fraction
To convert a decimal back into a fraction, write the decimal over its place value (for instance, 0.75 becomes ( \frac{75}{100} )) and simplify if possible.
Example:
- 0.75 = ( \frac{75}{100} = \frac{3}{4} )
From Fraction to Percentage
To convert a fraction to a percentage, divide the numerator by the denominator, and then multiply by 100.
Example:
- ( \frac{3}{4} = (3 ÷ 4) × 100 = 75% )
From Percentage to Fraction
To convert a percentage back into a fraction, write the percentage number over 100 and simplify.
Example:
- 75% = ( \frac{75}{100} = \frac{3}{4} )
From Decimal to Percentage
To convert a decimal to a percentage, simply multiply by 100.
Example:
- 0.75 × 100 = 75%
From Percentage to Decimal
To convert a percentage back into a decimal, divide by 100.
Example:
- 75% = ( \frac{75}{100} = 0.75 )
