Fraction numbers represent a part of a whole and are expressed in the form of a numerator (top number) over a denominator (bottom number).
They are used to describe portions, ratios, or divisions of objects or quantities.
Here are some types of fractions:

Explanation: We observe in image \$3/5\$ and \$9/4\$ that both are fractions numbers.

In a proper fraction, the numerator is smaller than the denominator. This means the fraction represents a value less than 1.

Explanation: Here, we observe in the image \$3/5\$ is the proper fraction as 3 is smaller than 5.

An improper fraction has a numerator that is equal to or greater than the denominator. It represents a value greater than or equal to 1.

Explanation: Here, we observe in the image \$9/4\$ is the improper fraction as 9 is larger than 4.

A mixed number is a combination of a whole number and a proper fraction. It is expressed as a whole number followed by a proper fraction, like \$ 2 1/2 \$.

Explanation: Here, we observe in image 3 as a whole number and \$4/5\$ as a proper fraction. In both combinations, we get \$3 4/5\$ as a mixed fraction.
