Ratios, Equivalent Ratios, Ratio Tables

What does it mean for two ratios to be equivalent?

• They are always equal to each other.

• They represent the same relationship between quantities, meaning they simplify to the same fraction.

• They can be added together to form a new ratio.

• They must have the same numerator.

If the ratio of cars to SUVs is 5:2 and there are 70 total vehicles, how many SUVs are there?

• 10 SUVs

• 15 SUVs

• 20 SUVs

• 25 SUVs

What is the significance of the total in a ratio problem?

• It helps to determine the individual quantities when working with ratios, allowing for the calculation of missing values.

• It is used to simplify the ratio to its lowest terms.

• It indicates the maximum value that can be achieved in the ratio.

• It serves as a reference point for comparing different ratios.

How do you complete a ratio table?

• By randomly guessing the missing values

• By using known ratios to find missing values while maintaining the same relationship between the quantities.

• By adding all the values together

• By multiplying the values by a constant factor

If the ratio of red pens to blue pens is 2:5 and there are 40 blue pens, how many red pens are there?

• 12 red pens

• 16 red pens

• 20 red pens

• 24 red pens

What is the relationship between ratios and fractions?

• Ratios can be expressed as fractions, where the first quantity is the numerator and the second quantity is the denominator.

• Ratios and fractions are completely unrelated concepts.

• Fractions can only be expressed as ratios when they are whole numbers.

• Ratios are always larger than fractions.

How do you find an equivalent ratio?

• By adding both terms of the ratio together.

• By multiplying or dividing both terms of the ratio by the same non-zero number.

• By taking the average of both terms of the ratio.

• By subtracting one term from the other.

How can you use a tape diagram to represent ratios?

• A tape diagram visually represents the parts of a ratio using rectangles to show the relative sizes of each quantity.

• A tape diagram is used to calculate the sum of all parts in a ratio.

• A tape diagram only represents whole numbers and cannot be used for fractions.

• A tape diagram is a method for writing ratios in decimal form.

If a ratio is 1:4, what is the equivalent ratio if both terms are multiplied by 3?

• 3:12 is the equivalent ratio.

• 2:8 is the equivalent ratio.

• 1:5 is the equivalent ratio.

• 4:16 is the equivalent ratio.
