A percent is a way of expressing a number as a fraction of 100. It is denoted by the symbol '%'.

To calculate the percentage of a number, multiply the number by the percentage (in decimal form) and then divide by 100.

Part = (Percentage / 100) * Whole.

Percentage of incorrect answers = (Number of incorrect answers / Total number of answers) * 100.

Grade Percentage = (Number of correct answers / Total number of questions) * 100.

(12 / 15) * 100 = 80%.

Number of students who voted = (60 / 100) * 25 = 15 students.

Number of games won = (80 / 100) * 10 = 8 games.
