Understanding Fractions and Percentages

Before diving into the calculation, let's refresh our understanding of fractions and percentages.

Fraction: A fraction represents a part of a whole. It's written as a numerator (top number) over a denominator (bottom number), like 8/15. This means 8 parts out of a total of 15 parts.
Percentage: A percentage is a fraction expressed as a number out of 100. It uses the "%" symbol to indicate it's a part of a hundred. For example, 50% means 50 out of 100.
