The Basics of Fractions and Percentages

It consists of a numerator (the top number) and a denominator (the bottom number). The numerator indicates how many parts are being considered, while the denominator represents the total number of equal parts in the whole.

A **percentage**, on the other hand, is a way of expressing a part of a whole as a fraction of 100. The symbol “%” represents “out of one hundred.” So, 50% means 50 out of every 100.
