FAQ

What is a percentage?

A percentage is a way of expressing a number as a fraction of 100. It is often used to compare relative sizes of quantities or to describe proportions. For example, if you have a class of 50 students and 10 of them are left-handed, you could say that 20% of the students are left-handed.


How do you calculate a percentage?

To calculate a percentage, divide the part (the quantity of interest) by the whole (the total quantity), then multiply the result by 100. For instance, if you scored 45 out of 60 on a test, divide 45 by 60 to get 0.75, then multiply by 100 to get 75%. So, you scored 75% on the test.


Why are percentages important?

Percentages are crucial in various fields such as finance, statistics, and everyday life. They help in understanding proportions, comparing different quantities, and making informed decisions. For example, knowing the percentage increase in sales can help a business make strategic decisions, and understanding percentage discounts can help consumers make better purchasing choices.
