At the local aquarium, there are 10 dolphins, 8 penguins, and 4 whales. what is the ratio of penguins to whales? a) 1: 2 b) 2: 5 c) 2: 1 d) 2: 5

C is your answer also if u need  more help just message me or i will message u just ask

The answer is C because the ratio of penguins to whales is 8:4 because there are 8 penguins and 4 whales but then you have to simplify it.  So 8 divided by 2 is four and 4 divided by 2 is 2.  Then your ratio is 4:2 but you can still go smaller.  So then you take 4 divided by 2 equals 2 and 2 divided by 2 is 1.  So the ratio is answer C) 2:1
