A veterinarian has found that 4 cat years equal 32 human years, and 8 cat years equal 48 human years. Are cat years proportional to human years? Explain your reasoning.
No, because for them to be proportional they have to be equal, which they aren't say they were each cat year is 8 human years so the first is right but for the second one to be right it has to be 64. Hope this helps you out.
