Fraction Conversion

Definition

Fraction conversion is the process of changing a fraction into another form, such as a decimal or percent. This concept is essential for understanding how to represent numbers in different ways, particularly when dealing with percentages, as it allows for easy comparisons and calculations in various contexts.

5 Must Know Facts For Your Next Test

1. To convert a fraction to a percentage, multiply the fraction by 100 and add a percent sign. For example, converting 1/4 involves calculating (1/4) * 100 = 25%.
2. When converting a percentage back to a fraction, you can write the percentage over 100 and simplify it. For instance, 75% becomes 75/100, which simplifies to 3/4.
3. Understanding fraction conversion is vital for real-life applications, like calculating discounts during shopping or determining test scores as percentages.
4. It is crucial to recognize that not all fractions can easily convert to terminating decimals; some result in repeating decimals, which may require further simplification.
5. Visual aids like pie charts can help understand fraction conversion by illustrating how different fractions represent parts of a whole.
