the ratio of cats to dogs is 2:1 and the ratio of dogs to parrots is 15:2. in addition the ratio of parrots to snakes is 3:1. And the ratio is 6:7. What is the ratio of cats to turtles?

Answer 1

1 dog
2 cats
2/15 of a parrot
2/45 of a snake

I suppose you mean to say
6 snakes for 7 turtles
in which case
2/45 *7/6 = 7/135 turtles

so cats/turtles = 2 /(7/135) = 270/7
