Introduction to percentage:
In Math subject, a percent (percentage) is one way of expressing a number as a fraction number of 100. It means one per hundred. The percent is using the sign “%”. Example, 69% (to read this number “sixty-nine percent”) is equal to 69 / 100, otherwise 0.69. So, in this way of math percent help now for us. The percentage sign or symbol is “%”.

Math Percent help:
The percentages are mostly helpful now, it is used and expressed how large quantity and small quantity is, related to another quantity. It has using two quantities; usually the first quantity represents the part of second quantity. And it should be greater than zero.
Example:
Increase of `$ 0.15` on a rate of `$1.50 ` an increase by a fraction of 0.15 / 1.50 = 0.1. So, that 0.1 * 100 = 10%, as a percentage expressed as, this is a 10% increase.
And also percentages helps to find and express numbers between zero and one, any dimensionless proportionality can be expressed as a percentage. For example, 129% is 1.29 and -0.29% is -0.0029.
Calculate the percentage:
The concept of performing calculations with percentages is, the percent symbol can be treated as being equivalent to the number constant 1 / 100 = 0.01. , for an example 75% of 400 can be written as (75 / 100) × 400 = 300.
Unit represents:
To find the percentage of a unit represents out of a whole of N units, divide 100% by N. For suppose, if we have 125 apples, and we want to find out what percentage of these 125 apples.
In a single apple represents, 100 / 125 = (100 / 125) % the answer of 0.8%.
So, if you give away one apple, you have given away 0.8% of the apples we had.
Then, if we give away 100 apples, we have given away 100 × 0.8% = 80% of us 125 apples.

Example problems in math percentage:
Example 1:
What is the answer for 300% of 40?
Solution:
300% × 40 = (300 / 100) × 40 = 120.
Answer is 120.
Example 2:
What is the solution of 15% of 75?
Solution:
15% × 75 = (15 / 100) × 75 = 11.25
Answer is 11.25.
Example 3:
75% of all college students are male. There are 1500 male students. How many (total) students are in the college?
Solution:
1500 = 75% × X, therefore X = (1500 / (75 / 100)) = 2000.
Answer is 2000.
