There are 30 North American butterflies at the butterfly park. Question A. How many South American butterflies are there? B. How many European butterflies are there? Please help answer both questions. Thx
NA : SA = 5 : 3 , SA : E = 3 : 2
So, NA : SA : E = 5 : 3 : 2 = 5x : 3x : 2x
given: NA = 30
5x = 30
x = 6
then NA = 30
SA = 18
E = 12
