This video tutorial covers the concept of equivalent ratios, comparing them to equivalent fractions. It includes exercises with dot patterns and a tuna casserole recipe to illustrate how to calculate and adjust ratios. The video also explains how to determine if ratios are equivalent and provides examples and non-examples. Students are encouraged to practice and verify their understanding of equivalent ratios.

What is a key strategy to keep in mind when solving equivalent ratios?

• Using division to simplify

• Subtracting smaller numbers from larger ones

• Comparing them to equivalent fractions

• Using addition to find common terms

How many cups of pasta are needed for one batch of tuna casserole?

• 4 cups

• 3 cups

• 2 cups

• 5 cups

If you want to make half the amount of casserole, what should you do with the ingredients?

• Multiply by 2

• Divide by 2

• Subtract 2 from each

• Add 2 to each

What is the ratio of cups of pasta to ounces of tuna in one batch?

• 3:7

• 3:6

• 3:5

• 3:4

How many batches can be made with 9 cups of pasta and 18 ounces of tuna?

• 1 batch

• 3 batches

• 2 batches

• 4 batches

What operation is primarily used to determine if two ratios are equivalent?

• Addition

• Division

• Multiplication

• Subtraction

Which of the following ratios is equivalent to 5:3?

• 10:6

• 15:10

• 20:12

• 25:18

What is a non-example of an equivalent ratio to 5:3?

• 20:12

• 15:9

• 10:6

• 9:6

How can you express the relationship between equivalent ratios and fractions?

• They both use addition

• They are unrelated

• They both involve multiplying or dividing by the same number

• They both use subtraction

What is the most important concept to remember about equivalent ratios?

• They can be found by adding the same number to both parts

• They are always smaller than the original ratio

• They can be found by multiplying or dividing both parts by the same number

• They are always larger than the original ratio
