Percent Problem Solving Techniques

This video tutorial explains how to solve percent problems using the proportion method. It introduces the concept of setting up a proportion with 'is' over 'of' equal to the percent over 100. Three examples are provided: finding the percent, finding the number, and dealing with percents over 100. The video emphasizes using cross products to solve these equations and highlights the importance of identifying the 'is', 'of', and percent values in a problem.

What is the main method discussed in the video for solving percent problems?

• Graphical method

• Proportion method

• Using a calculator

• Trial and error

In the proportion method, what does the 'is over of' ratio represent?

• The percentage

• The unknown value

• The total amount

• The relationship between two numbers

In the example '30 is what percent of 50?', what is the unknown value?

• 50

• The total

• The percent

• 30

How do you set up the proportion for '30 is what percent of 50?'

• 30/50 = P/100

• 50/30 = P/100

• P/30 = 50/100

• 30/100 = P/50

What is the result of solving the proportion 30/50 = P/100?

• 60%

• 70%

• 80%

• 50%

In the example '75% of 44 is what number?', what is the known percentage?

• 75%

• 44%

• 100%

• 50%

How is the proportion set up for '75% of 44 is what number?'

• N/44 = 75/100

• 44/N = 75/100

• 75/N = 44/100

• N/75 = 44/100

What is the result of solving the proportion N/44 = 75/100?

• 33

• 34

• 36

• 35

In the example '62 is 124% of what number?', what is the known percentage?

• 50%

• 124%

• 100%

• 62%

How is the proportion set up for '62 is 124% of what number?'

• 62/N = 124/100

• 124/N = 62/100

• N/62 = 124/100

• 62/124 = N/100
