### Example Question #1 : How To Find Percentage Equivalent To A Decimal

Sally sees a jacket on sale that's . The store is having a storewide discount. What is the price of the jacket after the discount is applied?      Explanation:

The original price of the jacket is $53 and there's a discount applied that's close to being 50% off. Therefore we know the right answer should be a little greater than$26.50. This allows for the elimination of $24,$23.85 and $8.63 as options for viable answers. This problem requires transitioning percentages into decimals as currency. In this case, it's helpful to keep in mind . Using the information given, this skeleton would look like . The intention of this is to see what 45% of$53.00 isThe is is what is being found, so it can be labeled as x. Using cross multiplication, x is calculated to be $23.85. X is what 45% of$53 is. Now the final calculation can be calculated through subtracting the x value from the jacket's original price .

### Example Question #2 : How To Find Percentage Equivalent To A Decimal

A high school senior takes a survey of the entire senior class for a project. She's interested in seeing the distribution of what her peers decide to pursue in college. She came up with the following data: The rest of the students stated an interest in Linguistics. How many students in total were surveyed?      Explanation: In this question, information about 5 groups of students is included but isn't expressed in the table nor is it expressed in terms of a percentage.

The sample the student took, despite how many students were interviewed, will have all the percents add up to 100% - as in the case with any study with percent breakdowns. The number of prospective Linguistic students is given (37), and it's know they're a part of the 100% the sample provides. To determine their percent, all the other intended majors percents must be subtracted from the total (100%). Once this information has been uncovered, this problem becomes a matter of being able to calculate what 37 is 6% ofThis can be uncovered through the use of . In this question, the percent and "is" is known. The goal is to find what the "of" is. The of will provide the total number of students surveyed. Denoting the "of" as x, substituting all information in, and undergoing cross multiplication will provide the final answer.   Given that fractions of a person cannot be surveyed, the final answer must be rounded to the nearest whole number.
