Understanding Ratios and Operations

The video tutorial explains how to fill a table of equivalent ratios by using known values to identify patterns. It emphasizes the importance of using multiplication for increasing values and division for decreasing values. The tutorial demonstrates how to verify the equivalence of ratios using a calculator and encourages students to double-check their work. By following these steps, students can confidently fill in missing values in a table of equivalent ratios.

What is the first step in filling a table of equivalent ratios?

• Use only division to find patterns

• Guess the missing values

• Make assumptions about the values

• Use information that is known for sure

Which operation is used to find patterns for increasing values?

• Addition

• Subtraction

• Multiplication

• Division

How do you verify if two ratios are equivalent?

• By checking if their sums are equal

• By adding the numbers in each ratio and comparing the results

• By checking if their products are equal

• By dividing the first number by the second in each ratio and comparing the results
