when buying lemonade mix, Cece spend $0.72 on a 6 - ounce packet and $0.27 on a 3 - ounce packet. Use unit rates to determine if each pair of rates is equivalent. Explain.

6 - ounce packet rate = $0.72.

In order to find the one ounce rate, we need to divide $0.72 by 6.

On dividing 0.72 by 6, we get $0.12.

Therefore, first unit rate is $0.12 per ounce.

3 - ounces packet rate = $0.27.

In order to find the one ounce rate, we need to divide $0.27 by 3.

On dividing 0.27 by 3, we get $0.09.

Therefore, second unit rate is $0.09 per ounce.

So, we can say that each pair of rates is not equivalent.
