how to calculate percentage ?

 Two values—the portion and the whole—are required to determine a percentage. The proportion of the part to the total is shown by the percentage. The formula for computing a percentage is as follows:

Percentage is equal to (Part/Whole) * 100.

In order to determine a percentage, do the following:

Choose the component: Determine the precise amount or value for which you wish to compute the percentage. We'll refer to this value as "X."

Identify the total: Find the entire amount or amount of which "X" is a component. We'll refer to this value as "Y."

Fill in the formula with the values: Multiply the result of dividing X by Y by 100.

X / Y * 100 equals percentage

Determine the outcome: Calculate the percentage using a calculator or by carrying out the mathematical procedures.

Here's an example:

Consider a class of 40 students in which 25 received A grades. To determine the proportion of students that received an A:

25 students received an A, therefore X (part) = 25

The total number of pupils, Y, is 40.

Percentage equals (25/40) * 100, or 0.625 * 100, for a percentage of 62.5%.

Consequently, 62.5% of pupils received an A or above.
