Question

jenny is comparing the cost of two packages of socks. one package has 8 pairs for $12. Another package has 3 for $6. Are the rates proportional?

Answer 1

In order to solve this we need to make on part of both statements equal.

Since 12 is divisible by 6 lets do that.

Multiply everything in the second package by 2.

It then becomes 6 pairs for $12.

So now  have have 6 or 8 pairs for $12.

You are getting a different amount for the same price therefore they are not proportional.
