1. Let's start by understanding what a fraction is. 2. A fraction represents a part of a whole or any number of equal parts. 3. It is written in the form $\frac{a}{b}$ where $a$ is called the numerator, representing how many parts you have, and $b$ is the denominator, representing into how many parts the whole is divided. 4. For example, $\frac{3}{4}$ means 3 parts out of 4 equal parts. 5. Fractions can be proper (numerator less than denominator), improper (numerator greater than or equal to denominator), or mixed numbers (a whole number combined with a fraction). 6. They are useful in representing quantities less than one, ratios, probabilities, and more.
