A fraction is a way to show part of a whole. Imagine you have a pizza and you want to share it with your friends. A fraction can help you show how much of the pizza each person gets.
For example, if you have a pizza and you want to share it equally with 3 friends, you would give each friend 1/3 of the pizza. The fraction 1/3 shows that each friend gets one piece of the whole, which is three pieces.
The top number of a fraction is called the numerator, and the bottom number is called the denominator. The numerator shows how many pieces you have, and the denominator shows how many pieces make up the whole.
So, a fraction is a way to show a part of a whole, and it can be written as a ratio of two numbers. Fractions are useful for dividing and comparing amounts, and they are a key part of mathematics.
