A percentage is a number or ratio expressed as a fraction of 100.

It is often denoted using the percent sign, “%”, or the abbreviations “pct.”, “pct”; sometimes the abbreviation “pc” is also used.

Ratio means comparing two quantities. For example, a basket has two types of fruits, say, 20 apples and 5 oranges Thus, the ratio of the number of oranges to the number of apples = 5 : 20 The comparison can be done by using fractions as,5 / 20=1 / 4 percentage of oranges 5 / 25×100=20% percentage of apples 20 / 25×100=80% The total sum of individual percentages is always equal to 100 = 20 + 80.
