To convert to percentage, you'll need to know the original value and the total or whole. For example, let's say you scored 80 points out of 100 on a test - to calculate the percentage, you'd divide 80 by 100 and multiply by 100 (or simply move the decimal point two places to the right)! Easy peasy, right?
But why bother with percentages, you might wonder? Well, my friend, it's all about context. Percentages help you see how different numbers relate to each other, making it easier to spot trends, patterns, and insights that might have gone unnoticed.
