Unit Rates and Equivalent Ratios

This video tutorial covers the concept of equivalent ratios, providing two examples to illustrate how to determine if pairs of rates are equivalent. The first example uses miles per hour, while the second example uses donuts per dollar. The video concludes with a prompt for viewers to try similar problems on their own to reinforce understanding.

What is the unit rate of 24 miles in 6 hours?

• 3 miles per hour

• 6 miles per hour

• 4 miles per hour

• 5 miles per hour

Are the rates 24 miles in 6 hours and 40 miles in 8 hours equivalent?

• They are equivalent only if the distance is halved

• They are equivalent only if the time is doubled

• No, they are not equivalent

• Yes, they are equivalent

How much does one donut cost if you buy four donuts for $12?

• $3

• $2

• $4

• $5

If you buy seven donuts for $21, what is the cost per donut?

• $2

• $3

• $5

• $4

Are the rates of four donuts for $12 and seven donuts for $21 equivalent?

• Yes, they are equivalent

• No, they are not equivalent

• They are equivalent only if the price is doubled

• They are equivalent only if the number of donuts is halved
