How to calculation Percentages

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

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

discover P percent the X find what percent the X is Y uncover X if p percent of it is Y

1. Exactly how to calculate percent of a number. Usage the percentage formula: P% * X = Y

Example: What is 10% of 150?

convert the problem to an equation making use of the percent formula: P% * X = Y p is 10%, X is 150, so the equation is 10% * 150 = Y convert 10% to a decimal by removed 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 execute the math: 0.10 * 150 = 15 Y = 15 so 10% the 150 is 15 twin check your answer through the original question: What is 10% that 150? multiply 0.10 * 150 = 15

2. How to find what percent that X is Y. Usage the percent formula: Y/X = P%

Example: What percent of 60 is 12?

transform the problem to one equation using the percent formula: Y/X = P% X is 60, Y is 12, therefore the equation is 12/60 = P% perform the math: 12/60 = 0.20 Important! The an outcome will constantly be in decimal form, not portion form. You need to multiply the result by 100 to get the percentage. Converting 0.20 come a percent: 0.20 * 100 = 20% so 20% of 60 is 12. Dual check her answer v the original question: What percent that 60 is 12? 12/60 = 0.20, and multiplying by 100 to acquire percentage, 0.20 * 100 = 20%

3. Exactly how to find X if ns percent of it is Y. Usage the percentage formula Y/P% = X

Example: 25 is 20% of what number?

convert the difficulty to one equation making use of the percentage formula: Y/P% = X Y is 25, P% is 20, so the equation is 25/20% = X convert the percentage to a decimal by splitting by 100. Convert 20% to a decimal: 20/100 = 0.20 instead of 0.20 for 20% in the equation: 25/0.20 = X do the math: 25/0.20 = X X = 125 so 25 is 20% of 125 double check her answer v the initial question: 25 is 20% of what number? 25/0.20 = 125

Remember: how to convert a portion to a decimal

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

Remember: just how to transform a decimal to a percentage

main point by 100 and add a percentage sign 0.876 = 0.876 * 100 = 87.6%

Percentage Problems

There space nine variations on the three an easy problems including percentages. Watch if you can enhance your trouble to among the samples below. The trouble formats match the input fields in the calculator above. Formulas and also examples room included.


What is p percent that X?

composed as an equation: Y = P% * X The "what" is Y the we desire to deal with for psychic to very first convert percent to decimal, dividing by 100 Solution: solve for Y making use of the percent formula Y = P% * X

Example: What is 10% that 25?

Written utilizing the percent formula: Y = 10% * 25 first convert percentage to a decimal 10/100 = 0.1 Y = 0.1 * 25 = 2.5 for this reason 10% of 25 is 2.5
