A pet owner has 5 cats. Each cat has 2 ears and 4 paws.

1. Complete the double number line to show the numbers of ears and paws for 1, 2, 3, 4, and 5 cats.
2. If there are 3 cats in the room, what is the ratio of ears to paws?
3. If there are 4 cats in the room, what is the ratio of paws to ears?
4. If all 5 cats are in the room, how many more paws are there than ears?

Each of these is a pair of equivalent ratios. For each pair, explain why they are equivalent ratios or draw a representation that shows why they are equivalent ratios.

1. \(5:1\) and \(15:3\)
2. \(25:5\) and \(10:2\)
3. \(198:1,\!287\) and \(2:13\)
