Frequently Asked Questions (FAQs)
A percentage is a way of expressing a number as a fraction of 100. It’s often denoted using the percent sign (“%”) or the abbreviation “pct.”. For example, 50% means 50 out of 100, or half.
To calculate X% of Y, you convert the percentage to a decimal by dividing X by 100, and then multiply it by Y. For instance, 10% of 100 is (10/100) * 100 = 0.1 * 100 = 10.
To find what percentage X is of Y, you divide X by Y, and then multiply the result by 100. For example, if you want to know what percentage 20 is of 80: (20 / 80) * 100 = 0.25 * 100 = 25%. So, 20 is 25% of 80.
Percentage Increase: ( (New Value – Original Value) / Original Value ) * 100
Percentage Decrease: ( (Original Value – New Value) / Original Value ) * 100
This calculates the relative change between two numbers expressed as a percentage.
