In mathematics, a percentage is a ratio that represents a fraction of 100. It is one of the most common ways to express proportions in daily life, business, and education. Percentages are denoted by the symbol %. For example, 35% means 35 out of 100.
The basic formula of percentage is:
P × V1 = V2
Example: If 25 out of 50 students are male, then the ratio is 0.5. Multiply by 100 → 0.5 × 100 = 50%.
Percentage Difference = |V1 - V2| ÷ ((V1 + V2)/2) × 100
Example: |10 - 6| ÷ (10 + 6)/2 = 4 ÷ 8 = 0.5 = 50%.
To calculate increase or decrease:
Example: 500 increased by 10% = 500 × (1 + 0.1) = 550
500 decreased by 10% = 500 × (1 – 0.1) = 450
