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
Read on come learn an ext about exactly how to number percentages.

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 decimalremove the percentage sign and also divide through 100 15.6% = 15.6/100 = 0.156
Remember: exactly how to convert a decimal to a percentagemain point by 100 and include a portion sign 0.876 = 0.876 * 100 = 87.6%
