# Percentage is a way of expressing a number as a fraction of 100. The formula to calculate percentage is as follows

Percentage = (Part / Whole) x 100

Where “Part” is the quantity or amount you want to express as a percentage and “Whole” is the total quantity or amount that you are using as the base.

Here’s an example:

Suppose you scored 80 out of 100 on a test. To find out your percentage score, use the formula:

Percentage = (80 / 100) x 100 = 80%

So, in this example, your score is 80%.

Another example:

2 If you want to find the percentage of 20 out of 200, the formula will be: (20/200) x 100 = 10%

3 If you want to find the percentage of 50 out of 1000, the formula will be: (50/1000) x 100 = 5%

4 If you want to find the percentage of 30 out of 300, the formula will be: (30/300) x 100 = 10%

5 If you want to find the percentage of 40 out of 400, the formula will be: (40/400) x 100 = 10%

6 If you want to find the percentage of 25 out of 250, the formula will be: (25/250) x 100 = 10%

7 If you want to find the percentage of 60 out of 600, the formula will be: (60/600) x 100 = 10%

8 If you want to find the percentage of 70 out of 700, the formula will be: (70/700) x 100 = 10%

9 If you want to find the percentage of 80 out of 800, the formula will be: (80/800) x 100 = 10%

10If you want to find the percentage of 90 out of 900, the formula will be: (90/900) x 100 = 10%
