What is a fraction?
A fraction is a part of a whole. It tells us how many parts of a whole we have.
For example, out of four pieces of a watermelon, you get one piece, the fraction you have is one quarter i.e. ¼ (one out of four).
The top part of the fraction is called the numerator. It shows the number of parts that you have.
The bottom part of the fraction is called the denominator. It shows the total number of parts the whole is divided into.
What is a unit fraction?
Unit means one. A unit fraction is a fraction where the numerator (the number on the top of the fraction) is 1. The denominator (on the bottom) can be any other whole number.
What is a non-unit fraction?
A non-unit fraction is a fraction where the numerator (the number on the top of the fraction) is any number other than 1. The denominator (the number on the bottom of the fraction) can be any other whole number.
