Answer:
"The ratio of the number of cats to dogs is 3:5. How many dogs would there be if there were 12 cats?"
Reworded, this says that "for every 3 cats there are 5 dogs." Or else you could say, "for every 5 dogs there are 3 cats."
You are given the number of cats=12. For every 3 cats there are 5 dogs." That means 50 dogs.
(3 cats) / (5 dogs) = (12 cats) / (x dogs)
3 / 5 = 12 / x
3x = 5*12
3x = 60
x = 20 dogs
Or you could write:
(5 dogs) / (3 cats) = (x dogs) / (12 cats)
x = 20 dogs.
