an animal shelter has a ratio of dogs to cats test 3:2 if they are 30 cats at the shelter how many dogs are there
This ratio is in a form of dogs:cats. The ratio given means there are 3 dogs for every 2 cats. You can rewrite it as 3 dogs:2 cats. If there are 30 cats, you would write the ratio as x dogs:30 cats. Since the same must be done to both sides, you must find how many times 2 was multiplied to get 30 then multiply dogs by that number. 30 / 2 = 15 3 • 15 = 45 So if a shelter has 30 cats, then it has 45 dogs. This can be written in a ratio as 45:30, or 45 dogs:30 cats.
