The Basics of Percentages
Before diving into our main question, let’s clarify what a percentage is. A percentage is a ratio expressed as a fraction of 100. Essentially, it helps us compare numbers relative to a whole.
For instance, if you want to know how much 27 is of 75, the formula for calculating percentage is:

]
Breaking It Down: Applying the Formula
To find what percent of 75 is 27, we’ll plug the numbers into our formula:
- Part = 27
- Whole = 75
Using the formula, we have:
[
\text{Percentage} = \left( \frac{27}{75} \right) \times 100
]
Solving it step-by-step:
- Division: ( \frac{27}{75} = 0.36 )
- Multiplication: ( 0.36 \times 100 = 36 )
Thus, 27 is 36% of 75.
