Understanding Fractions
Learn what fractions are and how to represent parts of a whole.
Introduction
Fractions are one of the most important concepts in mathematics. A fraction represents a part of a whole or a part of a group. Understanding fractions is essential for more advanced math topics.
What is a Fraction?
A fraction has two parts: the numerator (top number) and the denominator (bottom number). The denominator tells us how many equal parts the whole is divided into, and the numerator tells us how many of those parts we have.
Example
In the fraction 3/4, the denominator 4 means the whole is divided into 4 equal parts, and the numerator 3 means we have 3 of those parts.
Visualizing Fractions
We can visualize fractions using shapes like circles or rectangles divided into equal parts. This helps us understand what the fraction represents.
Example
A pizza cut into 8 slices where you eat 3 slices can be written as 3/8.
Types of Fractions
There are three main types: proper fractions (numerator < denominator), improper fractions (numerator ≥ denominator), and mixed numbers (whole number + fraction).
Example
2/3 is proper, 5/3 is improper, and 1⅔ is a mixed number.
