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 decimaleliminate the portion sign and divide through 100 15.6% = 15.6/100 = 0.156
Remember: exactly how to transform a decimal to a percentagemultiply by 100 and include a portion sign 0.876 = 0.876 * 100 = 87.6%
