Understanding Proportional Tables and Factors

The video tutorial explains how to determine if a table is proportional or non-proportional by checking for a constant rate of multiplication. It provides examples of both proportional and non-proportional tables, highlighting the importance of consecutive X values and consistent multiplication rates. The tutorial concludes with an example involving trips and miles to illustrate a proportional relationship.

What is a key characteristic of a proportional table?

• The values increase by addition.

• The values decrease by subtraction.

• The values are multiplied by a constant rate.

• The values are divided by a constant rate.

Why is it important to check if X values are in consecutive order?

• To ensure the table is colorful.

• To make the table look neat.

• To ensure no numbers are skipped.

• To make calculations easier.

In a proportional table, what should be consistent across all entries?

• The multiplication factor.

• The subtraction factor.

• The addition factor.

• The division factor.

What is the multiplication factor in the first proportional table example?

• 15

• 12

• 20

• 10

What is the result of 3 multiplied by the constant rate in the first proportional table example?

• 30

• 35

• 40

• 45

What indicates a table is non-proportional?

• The values are all even numbers.

• The table has more than 10 entries.

• The values are in alphabetical order.

• The multiplication factor changes.

In the example of a non-proportional table, what was incorrect?

• The subtraction factor was too low.

• The multiplication factor was inconsistent.

• The division factor was inconsistent.

• The addition factor was too high.

What should you do if the multiplication factor is not constant in a table?

• Consider the table non-proportional.

• Ignore the table.

• Consider the table proportional.

• Recalculate the values.

In the non-proportional table example, what was the incorrect result for 9 multiplied by the factor?

• 50

• 65

• 55

• 60

What is the multiplication factor in the proportional table example with trips and miles?

• 20

• 15

• 12

• 10
