Understanding Percent Proportions

This video tutorial explains how to solve basic percent problems using the percent proportion method. It begins by introducing the concept and setting up the proportion by converting the given percentage into a fraction with a denominator of 100. The tutorial then demonstrates how to identify the 'is' and 'of' components, assign a variable to the unknown, and solve the equation by cross-multiplying. The example problem 'What is 24% of 325?' is solved step-by-step, resulting in the answer 78. The video concludes with a brief mention of the next type of percent problem to be covered in the following video.

What is the first step in solving basic percent problems using percent proportion?

• Write the percentage as a fraction with a denominator of 100.

• Multiply the percentage by the number.

• Convert the percentage to a decimal.
