What is a Fraction?
A fraction often represents a part of a whole or a part of a set.
The fraction is always made up of a numerator and a denominator.
The denominator is the number below the fraction bar (line). It represents the number of equal parts into which the whole has been divided.
The denominator of the fraction |\dfrac{1}{4}| means that the whole is divided into |4| equal parts.
The numerator is the number above the fraction bar. It represents the number of equal parts being used.
The numerator of the fraction |\dfrac{1}{4}| means that 1 part is used.
How can Fractions be Represented?
A fraction can be represented in different ways: using circles, rectangles, or a set of objects.

Comparing and Ordering Fractions
Ordering fractions means comparing them so they can be placed in ascending or descending order.

What is an Irreducible (Simplified) Fraction?
A fraction is in lowest terms when the numerator and the denominator have only 1 as a common divisor. The fraction is then in its simplest or irreducible form.

How can a Fraction be Multiplied by a Whole Number?
