Here you have an illustration so you can understand the meaning of fraction. Fractions have two different parts: numerator and denominator. We explain you what numerator and denominator are by separate.
What is the numerator?
Numerator represents how many fraction pieces you have from the total. In this example, (1/8) you get one piece of pizza from the 8 slices(total). So when you eat a slice of pizza, you are eating 1/8 of the pizza.
What is the denominator
Denominator represents how many fraction pieces your whole is broken into. In this example, 8 means that we have broken the pizza in 8 slices. The pizza is a whole wich is divided into eight slices. Every slice represents (1/8) of the pizza.
