How to calculation Percentages

There are numerous formulas for portion problems. You deserve to think that the most simple as X/Y = p x 100. The formulas listed below are every mathematical variations of this formula.

Let"s explore the three basic percentage problems. X and also Y are numbers and P is the percentage:

uncover P percent that X uncover what percent of X is Y discover X if ns percent of the is Y

1. How to calculate percentage of a number. Use the percentage formula: P% * X = Y

Example: What is 10% the 150?

transform the problem to an equation using the percent formula: P% * X = Y ns is 10%, X is 150, for this reason the equation is 10% * 150 = Y convert 10% come a decimal by remove the percent sign and dividing by 100: 10/100 = 0.10 instead of 0.10 because that 10% in the equation: 10% * 150 = Y i do not care 0.10 * 150 = Y perform the math: 0.10 * 150 = 15 Y = 15 so 10% that 150 is 15 double check your answer v the original question: What is 10% of 150? main point 0.10 * 150 = 15

2. Just how to find what percent the X is Y. Use the percentage formula: Y/X = P%

Example: What percent that 60 is 12?

convert the trouble to one equation using the percent formula: Y/X = P% X is 60, Y is 12, for this reason the equation is 12/60 = P% perform the math: 12/60 = 0.20 Important! The an outcome will constantly be in decimal form, not percentage form. You must multiply the an outcome by 100 to gain the percentage. Convert 0.20 come a percent: 0.20 * 100 = 20% therefore 20% the 60 is 12. Twin check your answer with the initial question: What percent that 60 is 12? 12/60 = 0.20, and multiplying by 100 to obtain percentage, 0.20 * 100 = 20%

3. Just how to uncover X if ns percent of that is Y. Use the portion formula Y/P% = X

Example: 25 is 20% that what number?

transform the trouble to one equation making use of the percentage formula: Y/P% = X Y is 25, P% is 20, therefore the equation is 25/20% = X transform the percentage to a decimal by dividing by 100. Converting 20% come a decimal: 20/100 = 0.20 instead of 0.20 because that 20% in the equation: 25/0.20 = X perform the math: 25/0.20 = X X = 125 therefore 25 is 20% the 125 dual check her answer through the initial question: 25 is 20% the what number? 25/0.20 = 125

Remember: exactly how to transform a portion to a decimal

remove the percentage sign and also divide by 100 15.6% = 15.6/100 = 0.156

Remember: exactly how to convert a decimal come a percentage

multiply by 100 and include a percentage sign 0.876 = 0.876 * 100 = 87.6%

Percentage Problems

There space nine sport on the three an easy problems entailing percentages. Check out if you can complement your difficulty to among the samples below. The difficulty formats enhance the input fields in the calculator above. Formulas and examples are included.


What is ns percent the X?

written as one equation: Y = P% * X The "what" is Y the we want to settle for mental to an initial convert percentage to decimal, splitting by 100 Solution: settle for Y utilizing the percent formula Y = P% * X

Example: What is 10% the 25?

Written making use of the percent formula: Y = 10% * 25 first convert percentage to a decimal 10/100 = 0.1 Y = 0.1 * 25 = 2.5 therefore 10% of 25 is 2.5
