Percentage and Ticket Problems

The video tutorial covers solving percent problems using the formula 'part equals percent times whole' and visual models like tape diagrams. It includes examples such as calculating the percentage of admission tickets made and determining the number of non-red candies in a bag. The tutorial emphasizes understanding the relationship between parts, percentages, and wholes, and provides step-by-step guidance on using both formulas and diagrams to solve these problems.

What is the formula used to find the part when given the percent and the whole?

• Part = Percent x Whole

• Part = Whole / Percent

• Part = Whole x Percent

• Part = Percent / Whole

If Haley has made 112 tickets out of a planned 320, what percent of the tickets has she completed?

• 45%

• 35%

• 25%

• 50%

In the example problem, what is the whole number of tickets Haley plans to make?

• 200

• 112

• 150

• 320

How do you convert a decimal to a percentage?

• Multiply by 100

• Add 100

• Divide by 100

• Multiply by 10

What is the purpose of using a tape diagram in solving percentage problems?

• To calculate the exact number of parts

• To avoid using formulas

• To visualize the relationship between part, percent, and whole

• To simplify the multiplication process

In the candy exercise, what is the total number of candies in the bag?

• 100

• 200

• 400

• 300

How many candies are not red if 28 out of 300 candies are red?

• 216

• 272

• 200

• 250

What is the percentage of candies that are not red in the bag?

• 30%

• 28%

• 72%

• 50%

What is the first step in solving a percentage problem using the formula?
