Frequently Asked Questions
A percentage is a way of expressing a number as a part of 100. In other words, it tells you how many parts out of 100 a certain quantity represents.
Percentages are often denoted by the symbol % written after the number. They can also be denoted by writing percent or pct after the number.
For example, 25% means 25 out of every 100, or 25/100 , which is equivalent to 0.25 in decimal form.
When you want to know what portion one value (the part) is of another value (the whole), use this formula:
Percentage = ( Part / Whole ) × 100
Example: If you have 25 defective items out of 200 total items, then
Percentage = ( 25 / 200 ) × 100 = 12.5%
This tells you that 12.5% of the items are defective.
Sometimes you may need to calculate the percentage change from an original (old) value to a new value. This is given by:
Percentage Change = ( (New Value - Old Value) / Old Value ) × 100
Example: If a product’s price increases from 50 to 65:
Percentage Change = ( (65 - 50) / 50 ) × 100 = ( 15 / 50 ) × 100 = 30%
This shows a 30% increase from the original price.
