Ratio Tables and Unit Rates

Determine if the rates are equivalent. Explain your reasoning.

• Since the rates have the same unit rate, they are not equivalent.

• Since the rates do not have the same unit rate, they are not equivalent.

• Since the rates do not have the same unit rate, they are equivalent.

• Since the rates have the same unit rate, they are equivalent.
