Mr. Finley’s class visited a number of freshwater lakes to learn more about the crocodiles and alligators living in them. The cl
ass counted the number of species in each lake as shown in the table. Lake Crocodiles Alligators A 4 5 B 21 35 C 3 9 D 6 16 E 24 30 The relationship between the number of crocodiles and the number of alligators is not proportional across all lakes. Only two of the lakes have crocodiles and alligators in the same proportion. Which two lakes are they?
Crocodile to alligator ratio in each lake: A: 4/5 B: 21/35 = 3/5 C: 3/9 = 1/3 D: 24/30 = 4/5 Thus, lakes A and D have crocodiles and alligators in the same proportion.
