Percent Problems and Student Statistics

In this video, Mr. J explains how to solve a percent problem using the percent equation: percent times the whole equals the part. The example involves calculating what percent of high school students are seniors. The process includes setting up the equation, calculating the total number of students, solving for the unknown percent, and rounding the result to the nearest percent. The video concludes with a summary of the solution and encourages viewers to check the description for more examples.

What is the basic equation used to solve percent problems?

• Whole - Part = Percent

• Percent + Whole = Part

• Whole * Part = Percent

• Percent * Whole = Part

What is the first step in solving a percent problem using the percent equation?

• Divide the part by the whole

• Multiply the percent by the whole

• Identify the whole and the part

• Add the percent to the whole

In the given problem, what is the unknown variable we are trying to find?

• The percent of seniors

• The number of seniors

• The total number of students

• The number of freshmen

How do we determine the total number of high school students?

• By adding the number of students in each class

• By subtracting the number of seniors from the total

• By multiplying the number of students in each class

• By dividing the number of seniors by the total

What is the total number of students in the high school?

• 193

• 720

• 167

• 188

What is the number of seniors in the high school?

• 193

• 172

• 188

• 167

What operation is used to isolate the variable 'p' in the equation?

• Addition

• Multiplication

• Division

• Subtraction

After solving the equation, what is the next step to find the percentage?

• Add 100 to the result

• Multiply the result by 100

• Subtract 100 from the result

• Divide the result by 100

What is the approximate percentage of seniors in the high school?

• 23%

• 20%

• 30%

• 25%

Why do we use the approximately symbol when stating the percentage of seniors?

• Because the percentage is rounded

• Because the number of students is an estimate

• Because the number of seniors is unknown

• Because the calculation was incorrect
