How To Calculate Percentage: It is an easy process to work out rates numerically. Occasionally, when finding the proportion or piece of an amount as part of another, you should communicate it as a rate.

How To Calculate Percentage?

Calculate the percentage

  1. Determine how the number will change to a rate. 
  2. Completing a numerical cycle on the number to be changed over to a rate 
  3. Increase the numerical interaction’s aftereffect by 100.

What is Percentage?

As a numerical measure, rates can either express as a number or a proportion. “%” or simply “percent” is the standard way to reference them.

Rate is derived from two words, “per” and “penny.” Cent is a Latin and French word that means “hundred,” and “percent” means “per hundred.” 

As an example, percent implies a certain percentage or a certain proportion of an entire. For instance, 90% implies 90 out of 100, while half (or half?) implies 30 out of 100. 

How to Quickly Calculate Percentages

The formula x percent = y percent of x can be used to quickly calculate percentages such as these. 

The rule says that 36% of 25 is the same as 25% of 36, so we can use our previous example.

Do you still think this is useful? Well, since 25% is equal to 1/4, we can see that 25% of 36 is 36/4 or 9. 25% of 36 is therefore a number of 9, and 36% of 25 must also be a number of 9.

This trick solves two problems for every one you solve! It is particularly useful when one of the problems is much easier to solve than the other.

Taking a moment to understand why this seemingly magical trick works can be helpful.

It is mentioned before that 36% equals 36/100. The fraction 1/100 can be written as decimal number 0.01 since it is a fraction.

36/100 also write as 0.01 x 36. The answer is (0.01 x 36) x 25 since 36% of 25 must equal 0.01.
