How to calculation Percentages

There are many formulas for percentage problems. You can think the the most straightforward as X/Y = ns x 100. The formulas listed below are every mathematical sport of this formula.

Let\"s discover the three straightforward percentage problems. X and also Y are numbers and also P is the percentage:

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

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

Example: What is 10% the 150?

transform the trouble to one equation using 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 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 perform the math: 0.10 * 150 = 15 Y = 15 therefore 10% that 150 is 15 twin check your answer through the original question: What is 10% the 150? multiply 0.10 * 150 = 15

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

Example: What percent of 60 is 12?

transform the trouble to one equation making use of the percentage formula: Y/X = P% X is 60, Y is 12, therefore the equation is 12/60 = P% carry out the math: 12/60 = 0.20 Important! The result will constantly be in decimal form, not portion form. You have to multiply the result by 100 to acquire the percentage. Converting 0.20 to a percent: 0.20 * 100 = 20% for this reason 20% of 60 is 12. Dual check her answer through the original question: What percent of 60 is 12? 12/60 = 0.20, and multiplying through 100 to acquire percentage, 0.20 * 100 = 20%

3. Just how to discover X if p percent of the is Y. Usage the portion formula Y/P% = X

Example: 25 is 20% the what number?

transform the trouble to an 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 splitting by 100. Convert 20% come 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% of 125 double check her answer v the original question: 25 is 20% the what number? 25/0.20 = 125

Remember: how to convert a portion to a decimal

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

Remember: how to transform a decimal come a percentage

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

Percentage Problems

There room nine sport on the three basic problems entailing percentages. See if girlfriend can complement your difficulty to one of the samples below. The difficulty formats complement the input areas in the calculator above. Formulas and also examples room included.

What is p percent of X?

created as an equation: Y = P% * X The \"what\" is Y the we desire to settle for remember to first convert percentage to decimal, dividing by 100 Solution: deal with for Y utilizing the percentage formula Y = P% * X

Example: What is 10% that 25?

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