The Basics of Fractions
Fractions are a fundamental part of mathematics. They represent a part of a whole, and are usually written as one number on top of another, separated by a line. The number on top is called the numerator, while the number on the bottom is called the denominator. For example, in the fraction 3/5, 3 is the numerator and 5 is the denominator.
