Understanding Unit Rates

What is the main difference between a rate and a ratio?

• A rate compares two quantities with the same units.

• A rate compares two quantities with different units.

• A ratio compares two quantities with different units.

• A ratio is always expressed as a fraction.

How do you convert a rate to a unit rate?

• Subtract the denominator from the numerator.

• Add the numerator and denominator together.

• Divide both the numerator and denominator by the same number.

• Multiply both the numerator and denominator by the same number.

If you have $10 for 8 cans of soup, what is the unit rate per can?

• $2.00 per can

• $0.80 per can

• $1.25 per can

• $1.50 per can

What is the unit rate of 187 miles in 7 days?

• 25.7 miles per day

• 26.7 miles per day

• 28.7 miles per day

• 27.7 miles per day

Why is it important to include units when expressing a unit rate?

• Units make the rate more complex.

• Units are only needed in scientific calculations.

• Units help to clarify what is being compared.

• Units are not necessary for understanding the rate.

Which bottle of cleaner is cheaper per ounce: 12 oz for $4.50 or 16 oz for $6.56?

• 12 oz bottle

• 16 oz bottle

• Both cost the same per ounce

• Cannot be determined

How do you determine the cheaper product per unit when comparing two items?

• Compare the brand of each item.

• Compare the total cost of each item.

• Compare the unit rate of each item.

• Compare the size of each item.

If a snail moves 5 feet in 2 hours, how far will it move in 5 hours?

• 3.5 feet per hour

• 3 feet per hour

• 2.5 feet per hour

Why is it useful to convert rates to unit rates in problem-solving?

• It simplifies the comparison of different rates.

• It makes calculations more complex.

• It is only useful in mathematical theory.

• It is not useful in real-life applications.
