How to Calculate Percentages?

There are many formulae to solve the Percentage Problems. The most basic recipe is X/Y = 100 x P. This simple formula can be used to solve different percentage problems.

Let's first look at the basic percentage concepts. Here, X and Y represent numbers, and P is the Percentage.

  • Find out the Percentage of X
  • Find out what per cent of X is Y
  • If Y is P Percent, find X

Calculating the Percentage of a Number

To calculate the percentage of a number, use the simple formula P% * X =

Example: How much is 20 per cent of 150?


  • The given problem can be converted to the equation Percentage Formula P% X = Y
  • It is P =20%, X = 150
  • Simply divide the value 20/100 =0.2 to convert 20% to a decimal value.
  • Substitute 0.2 for 20% in the equation, i.e. 0.2*150=Y
  • You can perform the multiplication operation by i.e. Y= 30

Therefore, 20% of 150 equals 30

How do you find out what Percentage of X is Y?

Use the formula to find out what Percentage of X is Y.

Example: What Percent of 40 Is 12?


  • Use the percentage formula Y/X = % to convert the problem.
  • Given the values X = 40, Y = 12, the equation becomes 12/40=P%
  • Basic maths will give you the decimal result, i.e. 12/40= 0.3
  • To change the decimal value to Percent, multiply the decimal number with 100. 0.3*100 =30%

So, 30 x 40 equals 12

How do you find X if Y is P per cent?

If P Percent is Y, you can find X using the formula Y/P% =X

Example:50 equals 20% of what number


  • The percentage formula Y/P% =X can be used to modify the problem.
  • According to the formula, Y =50, P% =20, so the equation becomes 50/20% =X
  • Divide 100 by Percent to convert percentages to decimals, i.e. 20/100=0.2
  • Substitute 50/0.2=X for the decimal value.
  • You can get the value for X by performing the basic Maths. It is 250

Therefore, 50 is 20% of 250.

What's the P Percentage of X?

These guidelines will help you determine how much P Percent of X is.

  • We need to solve the problem using Y. Write the following equation: Y = P% *X.
  • Do not forget to divide the Percent to a decimal by 100.
  • Use the formula Y = P% X to find the value of Y.

Example: What's 20% of 50?


Use the Percent Formula to rewrite the problem.

  • According to the formula, Y =20%*50
  • You can change the per cent value to a decimal form, i.e. 20/100 = 0.2
  • Add 20% to the equation, and Y = o.2*50 10

So 20% of 50 equals 10

What Percentage of X?

For the procedure to determine Y is What Percentage of X, see this link

  • Write the equation as Y = %? X
  • We need to figure out what P% is.
  • Divide the equation in half, leaving P% on one end.
  • The equation is now Y/X = (P%?). X) / P% becomes Y / P%, the same as Y/X.

Example: What Percent of 40?


  • Simply change the values according to the formula. P% = 15 / 40
  • P% = 15 / 40 = 0.375
  • Multiply the decimal result to Percent by multiplying it with 100
  • P% =0.375*100 = 37.5%

So 15 is 37.5% off 40

Y = P per cent of what?

To determine if Y is P per cent of what, follow the easy steps below

  • P Percentage of what is Y = % * X is the equation for Y
  • This is where we have to find the value of X.
  • Divide each side by P% to get X.
  • Y = P% = (P%xX) / Y becomes Y = P% = X and it is the exact same as X = P%.

You can thus solve for X by using the formula X = Y / %

Example:11 is 50% of what?


  • The formula allows you to rewrite the values given. X = 11/ 50%
  • Convert Percent to a decimal value, i.e. 50/100=0.5
  • In the equation X = 11, place decimal value at 50%.
  • So, by simplifying, we can get X = 22

Also, 11 is half of the 22

What Percentage of X Is Y?

These guidelines will help you determine what Percent of X is Y.

  • To determine what Percent of X is Y, the equation is P% *X = Y
  • It is important to determine what % P is.
  • Divide each side with X to get P% on one side.
  • (P% *X) /X = Y/X becomes P% =Y/X
  • Use the formula P% =Y/X to solve for P%

Example: How Much of 35 Is 5?


  • Use the formula P% = 5/35 to express the values.
  • Simple math will give you 5/35 = 0.1428
  • Convert Decimal to Percent: Multiply the decimal value 0.1428 by 100
  • The equation is P% = 0.1428*100 = 14.28%

Thus, 14.28% is 5.

Per cent of what's Y

These are the easy steps to finding P per cent of Y.

  • Simply write P% x = Y.
  • It is important to define what X is.
  • Divide each side by P% to get X on the other side.
  • (P% xX) / Y = P% / Y = P% Making it X = P% / Y = P%
  • Use the formula X = P% to solve for X

Example: What is 15?


  • The formula X = 15/30 allows you to rewrite the values.
  • Divide 30 by 100 to convert the Percentage Value into a decimal number, i.e. 0.3
  • The decimal value of the equation should be replaced with, i.e. X = 15/0.3
  • Basic math gives us the importance of X = 50

P Percentage of X is...

Follow these simple steps to determine if P Percent of X =

  • The equation to calculate the P Percentage of X is P% *X = Y
  • It is essential to decide on what Y is.
  • Use the Percentage Formula to solve the value of Y. Y = P% *X

Example: What is the difference between and?


  • The formula 6% * 30 = 1: Rewrite the values given.
  • Change the percentage value to decimal, i.e. 6/100=0.06
  • Substitute decimal for percentage in the equation, i.e. 0.06*30
  • The value of Y is therefore 0.06*30 = 1.81

Therefore, 6% of 30 equals 1.8

What is the P per cent of?

Here are some guidelines for determining Y of what P Percent is.

  • Formula to calculate Y of What is the P Percent? Y = P%
  • It is necessary to determine the value for X.
  • Multiply with X both ways to remove the X from the denominator.
  • (Y /X) *X = P%* X, making it Y = % *X
  • Divide the equation into both sides with P% to get X on one side.
  • Y/P% = (P%* X/P% making the equation for = Y/P%

Use the formula X = P% to solve the value of X

Example: 8. What is 12%?


  • The formula X = 8/12% will give you the values.
  • Divide 100 by 100 to convert the percentage into a decimal value, i.e. 12/100 =0.12
  • Substitute decimal value for equation, and X = 8/0.12
  • So, X =66.66

8 of 66.66 equals 12%
