Percentages are very useful to make calculations easier and to understand numbers and the differences between them. It's much simpler to work with and understand parts of 100 than it is to use fractions that often do not have an exact, non-recurring, decimal equivalent.
Since a percentage is really just a fraction where the denominator is 100, comparisons are easier too.
For working out the percentage of a number, like 3% of 73, we do these types of calculation all the time in real life. A few examples might be:
