30 % 100 = 30
Step 1: The output value is 100.
Step 2: Let’s imagine the unknown value as x.
Step 3: Consider the output value of 100 = 100%.
Step 4: In the Same way, x = 30%.
Step 5: On dividing the pair of simple equations we got the equation as under
100 = 100% (1).
x = 30% (2).
(100%)/(x%) = 100/30
Step 6: Reciprocal of both the sides’ results in the following equation:
x%/100% = 30/100
Step 7: Simplifying the above obtained equation further will tell what 30% of 100 is
x = 30%
Therefore, 30% of 100 is 30 🙂

Percentages are ratios written as a fraction of 100, a common denominator in mathematical expressions. Percentages are calculated by dividing a given number by the whole, then multiplying the result by 100. It is what a percentage of anything means: a part per hundred.
Multiplication in arithmetic is a commutative operation. Thus, the numbers used in a percentage computation can be reversed without changing the overall result.
A percent is a ratio expressed as a fraction of one hundred, making it a rational number because any rational number can be written as a fraction or divided into parts whose quotients can continue indefinitely or come to an end.
The percentage, the whole (or base), and the amount comprise the three components of a percent problem. The hidden secret could be any one of those constituents.
Percentage difficulties can be solved by substituting known values into the equation (Percent · Base = Amount) and solving for the unidentified numbers.
It's possible that your test score does not reflect your "true" grade. A percentage score is calculated by dividing the final score by the total possible points on the test and multiplying that result by 100.
Percentages are most commonly used to compare two numbers, with the second number being rebased to 100.
