Example problems to learn counting percentage
Here we will learn some example problems to count percentage.
Example 1
Write the fraction `30/100` as a percentage
Solution
Here 30 is expressed as a fraction of 100. To write `30/100` as a percent we have to multiply `30/100` by 100.
We, get `30/100` * 100 = 30
So, 30/100 is equal to 30 percentage or 30%
Example 2
Count the percent of 30 in 80
Solution
Here we have to count the percent of 30 in 80.
Let x be the percentage,
So, `30/80` = `x/100`
x = `30/80` * 100
x = `300/8`
x = 37.5
So, 30 is 37.5 percent of 80
Example 3
What is 30 percent of 20.
Solution
Here we have to find the value of 30 percent in 20
Let the number be x
So, `x/20` = `30/100`
x = `30/100` * 20
x = `600/100`
x = 6
So, 30 percent of 20 is 6.

Example 3: 25 is 4 percent of what number.
Solution
Let the number be x
So, `25/x` = `4/100`
This equation can be written as, x = `25/4` * 100
x = 25 * 25
x = 625
So, 25 is 4 percent of 625.
