Percentage, a term derived from the Latin word “per centum,” meaning “by the hundred,” is a way of expressing a fraction of 100. The basic formula for calculating percentage involves dividing a part by the whole and multiplying the result by 100. This simple formula serves as the foundation for more complex calculations.

Tips and Tricks

To make percentage calculations more efficient, consider using shortcuts. For example, multiplying by 1.5 can be mentally easier than calculating a 50% increase. However, it’s essential to be aware of common mistakes, such as confusing percentage change with percentage of a total, to ensure accurate results.
