A practical guide to fractions, decimals, and percentages. Whether you need to convert 3/4 to a decimal, find an equivalent fraction, or simplify a complex fraction, these pages walk you through it step by step.
What is a Fraction?
A fraction represents a part of a whole. It is written as one number over another, separated by a line. The top number is the numerator (how many parts you have) and the bottom is the denominator (how many equal parts the whole is divided into).
For example, 3/4 means you have 3 out of 4 equal parts. As a decimal, that is 0.75. As a percentage, that is 75%.
Types of Fractions
A proper fraction has a numerator smaller than its denominator (like 2/5). An improper fraction has a numerator larger than its denominator (like 7/4 = 1.75). A mixed number combines a whole number and a fraction (like 1¾).
Fractions in Everyday Life
You use fractions constantly without thinking about them. Cooking recipes, sale discounts, fuel gauges, map scales, and probability are all built on fractions. Being comfortable with fractions makes arithmetic in everyday situations much faster.
The Four Operations With Fractions
Adding and subtracting need a common denominator because you can only combine pieces of the same size. Multiplying and dividing don't, which is why they are often the easier two. The equivalent fractions guide shows how to rewrite fractions over a common denominator.
Fractions, Decimals and Percentages
These are three ways of writing the same amount. To turn a fraction into a decimal, divide the numerator by the denominator. To turn a decimal into a percentage, multiply by 100. Going the other way, a percentage is a fraction out of 100, so 35% = 35/100 = 7/20.
Full methods and a reference chart are in the fractions to decimals and decimal to fraction guides.
A Good Order to Learn Fractions
Equivalent fractions - the idea every other fraction skill depends on.
Simplifying fractions - reducing answers to lowest terms.
Mixed numbers and improper fractions - switching between forms like 1 3/4 and 7/4.
Fractions to decimals and decimals to fractions - moving between the two.
