What is a Percentage?
A percentage tells you how much of 100 something is. Because it breaks numbers down into a hundred small pieces, you can quickly see what part is being talked about. For instance, 50% means 50 parts out of 100 and is the same as half.

Percentages pop up everywhere-in sales discounts, test grades, sports stats, and bank interest-so they let people compare values the easy way. When you grasp percentages, tricky figures shrink to a size that makes sense.
How to Calculate Percentage Step-by-Step

Identify the Part and Whole
- Decide the amount you want as a percent (thats the part).
- Find the full total that the part comes from (thats the whole).
Divide the Part by the Whole
- Use a calculator or do long division to keep it clear.
Multiply by 100
Take that answer and multiply by 100.
Verify Your Work
- Read the numbers again to catch slips.
- If possible, check with a calculator so small mistakes dont creep in.
Tips and Tricks to Calculate Percentage Quickly
Use Easy Benchmarks: Keep 10%, 25%, 50%, 75% stored, because finding 10% is just cutting the number in ten parts.
Break It Down: Split hard numbers into small pieces. For instance, 18% becomes the simple trio of 10% + 5% + 3%.
Double and Halve: Grab 10% first, then cut that in half to land on 5%.
Use Multiples: For 20%, double the amount and park it by dividing 10.
Practice Mental Math: Just like shooting hoops, doing these baby drills again and again makes you faster.
