If 5 cats can catch 5 mice in 5 days, how many mice can they catch in one day?
Now, if 5 cats catch 1 mouse in 1 day, How many days would it take 1 cat to catch 1 mouse?
And finally, since 1 cat catches 1 mouse in 5 days, if you have three times as cats, they'll catch three times as many mice in the same amount of time.
So 3 cats catch ____ mice in 5 days.
