I think the answer is 25.5. Although, I don't know how you would have half a bike unless there was a 3 wheel bike which would make the answer 24.
700,000 + 70,000 + 70
is your answer
hope this helps :D
So 2:5 means that 5/7 animals are cats and 2/7 are dogs. I believe if you divide u will get your answer. 5/7 * 7/2 = 1.25x the number of dogs
