Percentage change measures how much a value has increased relative to its original value. This is commonly used for salary hikes, price changes, population growth, and exam score improvements.
The Formula
To find the percentage change between two numbers:
% Change = ((New Value - Old Value) ÷ Old Value) × 100
1
Find the difference: 50 - 40 = 10
2
Divide by original: 10 ÷ 40 = .25
3
Multiply by 100: .25 × 100 = 25%
Therefore, the percentage change from 40 to 50 is 25% increase.
