How to calculation Percentages
There are many formulas for portion problems. You can think the the most simple as X/Y = ns x 100. The formulas listed below are all mathematical variations of this formula.
Let"s check out the three straightforward percentage problems. X and also Y space numbers and P is the percentage:uncover P percent the X uncover what percent the X is Y uncover X if ns percent of that is Y

1. Just how to calculate percent of a number. Usage the percent formula: P% * X = Y
Example: What is 10% that 150?transform the problem to an equation making use of the percentage formula: P% * X = Y ns is 10%, X is 150, therefore the equation is 10% * 150 = Y convert 10% come 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 becomes 0.10 * 150 = Y carry out the math: 0.10 * 150 = 15 Y = 15 so 10% of 150 is 15 double check her answer v the initial question: What is 10% that 150? main point 0.10 * 150 = 15
2. Exactly how to discover what percent of X is Y. Use the percent formula: Y/X = P%
Example: What percent that 60 is 12?transform the problem to one equation making use of the percent formula: Y/X = P% X is 60, Y is 12, so the equation is 12/60 = P% perform the math: 12/60 = 0.20 Important! The result will constantly be in decimal form, not percentage form. You need to multiply the an outcome by 100 to gain the percentage. Convert 0.20 to a percent: 0.20 * 100 = 20% so 20% that 60 is 12. Double check your answer with the initial question: What percent of 60 is 12? 12/60 = 0.20, and multiplying by 100 to acquire percentage, 0.20 * 100 = 20%
3. Just how to find X if ns percent of the is Y. Usage the percent formula Y/P% = X
Example: 25 is 20% of what number?transform the problem to an equation using the percentage formula: Y/P% = X Y is 25, P% is 20, for this reason the equation is 25/20% = X convert the percent to a decimal by splitting by 100. Converting 20% to 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% that 125 dual check her answer v the initial question: 25 is 20% the what number? 25/0.20 = 125
Remember: exactly how to convert a portion to a decimalremove the portion sign and also divide by 100 15.6% = 15.6/100 = 0.156
Remember: how to transform a decimal come a percentagemain point by 100 and add a percentage sign 0.876 = 0.876 * 100 = 87.6%
