What is 72/100 as a percentage? It is 72.00%. The fraction 72/100 shows that 72 parts are taken out of a total of 100 equal parts. When we write that as a percent, we keep the same value but use the percent sign to make it clear that the base is one hundred.
Seeing the number as a percent makes it easy to compare with other percentages. For example, a score of 72.00% on a test means you got 72 out of every 100 points possible. It also tells you that the fraction is a little more than two‑thirds (which would be 66.67%).
In everyday life, you might see 72.00% used for discounts, interest rates, or statistics. If a store offers a 72.00% off sale, you would only pay 28% of the original price. The same idea works for any situation where a part of a whole is expressed in percent form.
