## Introduction to Fractions

A fraction is a way to represent parts of a whole. Fractions are written as one number over another number (e.g. ½ ). The bottom number (the denominator) represents the number of equal parts the whole has been divided into. The bottom number the numerator represents how many parts are included. This section will give you a brief introduction to fractions and explain some types of fractions that are important for you to know.
