Percentage
A percentage is a way of expressing a number, fraction, or ratio as a fraction of 100. It is denoted using the percent sign ($\%$), making it a convenient standard to compare different quantities relative to a common base of one hundred.
Example
If a student scores 45 out of 50 on a test, their score as a percentage is calculated as: $$ \frac{45}{50} \times 100\% = 90\% $$
