How to calculation Percentages
There are numerous formulas for portion problems. You deserve to think that the most simple as X/Y = p x 100. The formulas listed below are every mathematical variations of this formula.
Let"s explore the three basic percentage problems. X and also Y are numbers and P is the percentage:uncover P percent that X uncover what percent of X is Y discover X if ns percent of the is Y

1. 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 using the percent formula: P% * X = Y ns 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 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 so 10% that 150 is 15 double check your answer v the original question: What is 10% of 150? main point 0.10 * 150 = 15
2. Just how to find what percent the X is Y. Use the percentage formula: Y/X = P%
Example: What percent that 60 is 12?convert the trouble to one equation using the percent 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 constantly be in decimal form, not percentage form. You must multiply the an outcome by 100 to gain the percentage. Convert 0.20 come a percent: 0.20 * 100 = 20% therefore 20% the 60 is 12. Twin check your answer with the initial question: What percent that 60 is 12? 12/60 = 0.20, and multiplying by 100 to obtain percentage, 0.20 * 100 = 20%
3. Just how to uncover X if ns percent of that is Y. Use the portion formula Y/P% = X
Example: 25 is 20% that what number?transform the trouble to one equation making use of the percentage formula: Y/P% = X Y is 25, P% is 20, therefore the equation is 25/20% = X transform the percentage to a decimal by dividing 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 perform the math: 25/0.20 = X X = 125 therefore 25 is 20% the 125 dual check her answer through the initial question: 25 is 20% the what number? 25/0.20 = 125
Remember: exactly how to transform a portion to a decimalremove the percentage sign and also divide by 100 15.6% = 15.6/100 = 0.156
Remember: exactly how to convert a decimal come a percentagemultiply by 100 and include a percentage sign 0.876 = 0.876 * 100 = 87.6%
