Answer:
There are 48 South American butterflies.
Step-by-step explanation:
Given:
Ratio of North to South American butterflies = 8 : 4
Let the number of North American butterflies be [tex]8x[/tex].
So, South American butterflies = [tex]4x[/tex].
Now, as per question,
North American butterflies = 96
So, [tex]8x=96\\x=\frac{96}{8}=12[/tex]
Therefore, number of South American butterflies = [tex]4x=4\times 12=48[/tex]
Hence, there are 48 South American butterflies.
