Application of the calculator

  1. To calculate the percentage of a number, multiply the number by the percentage value as a decimal.
  2. Let us see this with an example — 10 is 5% of which number?
  3. Multiplying the result by 100 will yield the solution in percent, rather than decimal form.
  4. This calculation can help with many things, like figuring out sale prices or better understanding test scores.
  5. Mateusz and Dominik are experienced in creating scientific tools that solve everyday problems and explaining the concepts in a simple, easy-to-digest manner.

A teacher may be interested in seeing the fraction of the students who passed a given test in relation to the total number of students in the class. A project manager may be interested in knowing the fraction of the funds injected into the project that corresponds to the total funding. In all these cases, percentages are the best form for presenting such summaries. The iCalculate percentage calculator is a helpful tool for calculating percentages.

You should now know how to find the percentage of a number. If the discount is 10%, our calculator will tell us the original price is $48.89. In this article, we will discuss some examples of a percentage of a percentage (like what is 30% of 80%), and why the idea of “a percent of a percent” matters.

Let’s denote the numerator as “A” and the denominator as “B”. Saying that 50 percent of the students are girls is the same as saying that 1/2 of them are girls. Or if you prefer decimals, it’s the same thing as saying that 0.5 of all the students are girls. This example shows you that percents, like fractions and decimals, are just another way of talking about parts of the whole. In this case, the whole is the total number of children in the school.
