1. Exactly 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 utilizing the portion formula: P% * X = Y ns is 10%, X is 150, therefore the equation is 10% * 150 = Y transform 10% to a decimal by removing 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 therefore 10% the 150 is 15 dual check your answer v the original question: What is 10% the 150? main point 0.10 * 150 = 15

2. Just how to discover what percent of X is Y. Usage the portion formula: Y/X = P%

Example: What percent the 60 is 12?

transform the difficulty to an equation making use of the portion formula: Y/X = P% X is 60, Y is 12, so the equation is 12/60 = P% execute the math: 12/60 = 0.20 Important! The an outcome will constantly be in decimal form, not percent form. You need to multiply the an outcome by 100 to obtain the percentage. Convert 0.20 come a percent: 0.20 * 100 = 20% so 20% of 60 is 12. Dual check her answer v the initial question: What percent the 60 is 12? 12/60 = 0.20, and multiplying by 100 to obtain percentage, 0.20 * 100 = 20%

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

Example: 25 is 20% of what number?

convert the trouble to one equation utilizing the percent formula: Y/P% = X Y is 25, P% is 20, therefore the equation is 25/20% = X convert the percent to a decimal by dividing by 100. Converting 20% come a decimal: 20/100 = 0.20 instead of 0.20 for 20% in the equation: 25/0.20 = X execute the math: 25/0.20 = X X = 125 therefore 25 is 20% of 125 double check her answer with the original question: 25 is 20% that what number? 25/0.20 = 125

Remember: how to convert a percent to a decimal

eliminate the percent sign and also divide by 100 15.6% = 15.6/100 = 0.156

Remember: how to transform a decimal to a percentage

main point by 100 and include a portion sign 0.876 = 0.876 * 100 = 87.6%

Percentage Problems

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


What is p percent that X?

written as an equation: Y = P% * X The "what" is Y the we desire to resolve for remember to very first convert percent to decimal, splitting by 100 Solution: resolve for Y using the portion formula Y = P% * X

Example: What is 10% the 25?

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