The ratio of North American Butterflies to South American butterflies at a butterfly park is 7:5. The ratio of South American butterflies to European butterflies is 5:2. There are 70 North American butterflies at the butterfly park.

Answer 1

There are 70 North American butterflies, 50 South American butterflies, and 20 European butterflies.

Explanation:

NA butterflies: SA butterflies: E butterflies

7:5:2

To get 70 North American butterflies, you would have to multipy the ration by 10. As such, 5 times 10 = 50 and 2 times 10 = 20.
