Hint: In the given question, we are supposed to find 15 of 20. We start to solve the given question by multiplying the fraction 15 and a whole number 20. The product between the two will give us the required result.

Complete step-by-step answer:
We are asked to find 15 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:
ab
In the above fraction,
a is the numerator of the fraction
b is the denominator of the fraction
Example:
How do you reduce 14 by 16?
We need to multiply 14 and 16.
14×16
Cancelling out the factors, we get,
4
Now, we need to multiply 15 and 20.
15×20
From the above, we know that 20 is a whole number and 15 is a fraction
To multiply a whole number with a fraction, we need to convert the whole number into a fraction.
The whole number can be converted into a fraction with a denominator of one.
From the above, the whole number 20 can be written in fractional form as follows,
201
Substituting the above value, we get,
15×201
According to the rules of fractions,
The multiplication of fractions is done by multiplying the numerators and denominators of the fraction, respectively.
Applying the same, we get,
1×205×1
Simplifying the above fraction, we get,
205
Cancelling out the common factors, we get,
4
The value of 15 of 20 is 4.

Note: The result obtained in the given question can be cross-checked as follows,
The division of the result obtained and 15 must result in 20
From the above, the result obtained is 4
Substituting the same, we get,
4(15)
4×5
20
The result obtained is correct.
