Finding a Percent Using the Percent Proportion

The video tutorial explains how to use the percent proportion to find the part, whole, or percent when given the other two values. It introduces the formula 'is over of equals percent over 100' and demonstrates its application through an example problem: finding what percent 11 is of 55. The solution involves setting up the proportion, cross-multiplying, and solving for the unknown percent. The lesson concludes by reinforcing the understanding of using percent proportion to find a percent.

What does the 'is' represent in the percent proportion formula?

• The total

• The percent

• The part

• The whole

In the problem '11 is what percent of 55', what does the number 55 represent?

• The percent

• The part

• The whole

• The variable

How do you set up the proportion to find what percent 11 is of 55?

• 11 over 55 equals x over 100

• 11 over x equals 55 over 100

• 11 over 100 equals x over 55

• x over 11 equals 55 over 100

What is the result of cross-multiplying 11 over 55 equals x over 100?

• x = 5500

• x = 1100

• 55x = 1100

• 11x = 5500

After solving the proportion, what percent is 11 of 55?

• 25%

• 20%

• 15%

• 10%
