We are asked to find of 20. We will be solving the given question by finding out the product between the two given numbers.
The whole numbers are the numbers that include all the positive integers and zero. It does not include negative integers and fractions. They are also called the basic counting numbers.
A fraction, in mathematics, represents a part of a whole thing. It consists of two parts namely,
numerator, denominator.
The number on the top is called the numerator.
The number on the bottom is called the denominator.
Let us understand the concept of the fraction with an example as follows,
Example:
In the above fraction,
is the numerator of the fraction
is the denominator of the fraction
