If the ratio of cats to dogs in the veterinarian clinic is 2 to 3, which ratio does NOT show a possible number of cats to dogs in the clinic?

24 cats, 36 dogs

36 cats, 54 dogs

30 cats, 45 dogs

34 cats, 21 dogs

34 cats, 21 dogs

Step-by-step explanation:

34 cats, 21 dogs

34 : 21 is not equivalent to 2 : 3

34 cats, 21 dogs

Step-by-step explanation:

cats: dogs

2 : 3

Multiply by 12 to get 24 cats

2*12 = 24 3*12 = 36 so the first is correct

Multiply by 18 to get 36 cats

2*18 = 36 cats 3*18 = 54 dogs so the second is correct

Multiply by 15 to get 30 cats

2*15 = 30 3*15 = 45 so the third is correct

Multiply by 17 to get 34 cats

2*17 = 34 3*17 = 51 so the fourth is incorrect
