## How to calculation Percentages

There are many formulas for portion problems. You can think the the most simple as X/Y = ns x 100. The formulas listed below are all mathematical variations of this formula.

Let"s check out the three straightforward percentage problems. X and also Y space numbers and P is the percentage:

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

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

Example: What is 10% that 150?

transform the problem to an equation making use of the percentage formula: P% * X = Y ns is 10%, X is 150, therefore the equation is 10% * 150 = Y convert 10% come 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 becomes 0.10 * 150 = Y carry out the math: 0.10 * 150 = 15 Y = 15 so 10% of 150 is 15 double check her answer v the initial question: What is 10% that 150? main point 0.10 * 150 = 15

## 2. Exactly how to discover what percent of X is Y. Use the percent formula: Y/X = P%

Example: What percent that 60 is 12?

transform the problem to one equation making use of the percent formula: Y/X = P% X is 60, Y is 12, so the equation is 12/60 = P% perform the math: 12/60 = 0.20 Important! The result will constantly be in decimal form, not percentage form. You need to multiply the an outcome by 100 to gain the percentage. Convert 0.20 to a percent: 0.20 * 100 = 20% so 20% that 60 is 12. Double check your answer with the initial question: What percent of 60 is 12? 12/60 = 0.20, and multiplying by 100 to acquire percentage, 0.20 * 100 = 20%

## 3. Just how to find X if ns percent of the is Y. Usage the percent formula Y/P% = X

Example: 25 is 20% of what number?

transform the problem to an equation using the percentage formula: Y/P% = X Y is 25, P% is 20, for this reason the equation is 25/20% = X convert the percent to a decimal by splitting by 100. Converting 20% to a decimal: 20/100 = 0.20 instead of 0.20 because that 20% in the equation: 25/0.20 = X carry out the math: 25/0.20 = X X = 125 so 25 is 20% that 125 dual check her answer v the initial question: 25 is 20% the what number? 25/0.20 = 125

### Remember: exactly how to convert a portion to a decimal

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

### Remember: how to transform a decimal come a percentage

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

## Percentage Problems

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

### What is ns percent of X?

created as one equation: Y = P% * X The "what" is Y that we desire to deal with for psychic to first convert percentage to decimal, splitting by 100 Solution: resolve for Y using the percentage formula Y = P% * X

### Example: What is 10% of 25?

Written using the percentage formula: Y = 10% * 25 very first convert percent to a decimal 10/100 = 0.1 Y = 0.1 * 25 = 2.5 so 10% of 25 is 2.5
