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

Example: What is 10% that 150?

convert the difficulty to one equation utilizing the portion formula: P% * X = Y p is 10%, X is 150, for this reason the equation is 10% * 150 = Y convert 10% come a decimal by remove 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 carry out the math: 0.10 * 150 = 15 Y = 15 for this reason 10% of 150 is 15 dual check your answer with the initial question: What is 10% that 150? multiply 0.10 * 150 = 15

2. Just how to uncover what percent that X is Y. Use the percentage formula: Y/X = P%

Example: What percent the 60 is 12?

transform the trouble to an equation utilizing the portion 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 an outcome will always be in decimal form, not percent form. You should multiply the an outcome by 100 to gain the percentage. Converting 0.20 come a percent: 0.20 * 100 = 20% for this reason 20% that 60 is 12. Dual check your answer through the initial question: What percent that 60 is 12? 12/60 = 0.20, and also multiplying by 100 to get percentage, 0.20 * 100 = 20%

3. Exactly how to discover X if ns percent of that is Y. Use the percent 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 transform the percent to a decimal by separating by 100. Converting 20% to a decimal: 20/100 = 0.20 substitute 0.20 for 20% in the equation: 25/0.20 = X perform the math: 25/0.20 = X X = 125 so 25 is 20% the 125 twin check your answer with the original question: 25 is 20% of what number? 25/0.20 = 125

Remember: just how to transform a percentage to a decimal

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

Remember: exactly how to transform a decimal to a percentage

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

Percentage Problems

There space nine sport on the three basic problems including percentages. Watch if girlfriend can match your difficulty to one of the samples below. The difficulty formats match the input fields in the calculator above. Formulas and also examples room included.

What is ns percent the X?

created as an equation: Y = P% * X The "what" is Y that we want to solve for remember to an initial convert percentage to decimal, splitting by 100 Solution: fix for Y using the percentage formula Y = P% * X

Example: What is 10% that 25?

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