The query "how to find" is very broad and lacks specific context. However, based on search results primarily focusing on "how to find" related to percentages, here is a summary of common methods to find percentages:

How to Find a Percentage

  • The general formula to find the percentage of a part relative to a whole is:

Percentage=(PartWhole)×100\text{Percentage}=\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100Percentage=(WholePart​)×100

This calculates what percent the part is of the whole.

  • To find the part given a percentage and the whole:

Part=Whole×Percentage100\text{Part}=\text{Whole}\times \frac{\text{Percentage}}{100}Part=Whole×100Percentage​

For example, to find 60% of 9 cupcakes, convert the percentage to decimal (0.6) and multiply 9 by 0.6.

  • You can calculate a percentage mentally using combinations of 1%, 10%, and 50% as building blocks, adjusting by addition or subtraction.
  • When calculations involve fractions, convert the fraction to a decimal first, then multiply by 100 to find the percentage.

Examples

  • If you have 27 trees and 6 have pinecones, the percentage of trees with pinecones is:

(627)×100=22.22%\left(\frac{6}{27}\right)\times 100=22.22%(276​)×100=22.22%

  • To calculate the original value when given a percentage and part:

Whole=PartPercentage/100\text{Whole}=\frac{\text{Part}}{\text{Percentage}/100}Whole=Percentage/100Part​

For example, if 30% of a price is $120, then the original price is

1200.30=400\frac{120}{0.30}=4000.30120​=400
