Basic concepts of converting 27 out of 30 as a percentage

Before we get into the depths of the sum it is important for us to learn the basic concepts and definitions that are involved in the process and those are as follows:

1) A fraction (improper or proper) consists of two parts which are the numerator and the denominator. The numerator is the digit that is present above the line of division and the denominator is the digit that is present below the line of division.

2) Here, in this case, 27 is the numerator and the number 30 is the denominator.

3) Now as we need to define the concept of percentage, it is the method of expressing any numerical value in terms of 100. Or in other words, the digit is the fraction of 100. So if we take a simple example, the number 90% is the fraction 90/100.
