What is it?

Finding '50% of 10' means figuring out what half of the number 10 is. Percentage means 'out of 100', so 50% is like saying 50 out of 100, which simplifies to 1/2. When you find 50% of any number, you are simply finding half of that number.

Simple Example

Quick Example

Imagine you have 10 ladoos. If your friend says, 'Give me 50% of your ladoos,' it means they want half of them. So, you would give your friend 5 ladoos because half of 10 is 5.
