How to calculation Percentages

There are countless formulas for portion problems. You can think that the most basic as X/Y = p x 100. The formulas below are every mathematical sport of this formula.

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

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

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

Example: What is 10% of 150?

transform the problem to an equation making use of the percent formula: P% * X = Y ns is 10%, X is 150, for this reason the equation is 10% * 150 = Y convert 10% to a decimal by removing the percent sign and also dividing by 100: 10/100 = 0.10 instead of 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y execute the math: 0.10 * 150 = 15 Y = 15 therefore 10% of 150 is 15 twin check her answer with the original question: What is 10% the 150? main point 0.10 * 150 = 15

2. How to find what percent of X is Y. Use the portion formula: Y/X = P%

Example: What percent the 60 is 12?

convert the trouble to an equation using the percentage 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 always be in decimal form, not percentage form. You have to multiply the an outcome by 100 to get the percentage. Converting 0.20 to a percent: 0.20 * 100 = 20% therefore 20% of 60 is 12. Double check your answer v the original question: What percent the 60 is 12? 12/60 = 0.20, and multiplying through 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?

transform the difficulty to an equation utilizing the percentage formula: Y/P% = X Y is 25, P% is 20, so the equation is 25/20% = X convert the percent to a decimal by separating 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 do the math: 25/0.20 = X X = 125 therefore 25 is 20% of 125 double check her answer v the initial question: 25 is 20% that what number? 25/0.20 = 125

Remember: exactly how to convert a portion to a decimal

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

Remember: exactly how to convert a decimal to a percentage

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

Percentage Problems

There space nine sports on the three simple problems involving percentages. Watch if you can enhance your difficulty to among the samples below. The trouble formats match the input fields in the calculator above. Formulas and examples are included.

What is ns percent that X?

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

Example: What is 10% of 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 therefore 10% that 25 is 2.5
