1. Exactly 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 utilizing the portion formula: P% * X = Y ns is 10%, X is 150, therefore the equation is 10% * 150 = Y transform 10% to a decimal by removing 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 therefore 10% the 150 is 15 dual check your answer v the original question: What is 10% the 150? main point 0.10 * 150 = 15
2. Just how to discover what percent of X is Y. Usage the portion formula: Y/X = P%
Example: What percent the 60 is 12?transform the difficulty to an equation making use of the portion formula: Y/X = P% X is 60, Y is 12, so the equation is 12/60 = P% execute the math: 12/60 = 0.20 Important! The an outcome will constantly be in decimal form, not percent form. You need to multiply the an outcome by 100 to obtain the percentage. Convert 0.20 come a percent: 0.20 * 100 = 20% so 20% of 60 is 12. Dual check her answer v the initial question: What percent the 60 is 12? 12/60 = 0.20, and multiplying by 100 to obtain percentage, 0.20 * 100 = 20%
3. Exactly how to discover X if p percent of it is Y. Usage the percentage 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 convert the percent to a decimal by dividing by 100. Converting 20% come a decimal: 20/100 = 0.20 instead of 0.20 for 20% in the equation: 25/0.20 = X execute the math: 25/0.20 = X X = 125 therefore 25 is 20% of 125 double check her answer with the original question: 25 is 20% that what number? 25/0.20 = 125
Remember: how to convert a percent to a decimaleliminate the percent sign and also divide by 100 15.6% = 15.6/100 = 0.156
Remember: how to transform a decimal to a percentagemain point by 100 and include a portion sign 0.876 = 0.876 * 100 = 87.6%
