How many South American butterflies are there?

There are*blank* South American butterflies.

Answer 1

48 South American butterflies

Explanation:

Since the ratio of American butterflies to South American butterflies is 6:4, the unit rate for every North American butterfly would be 2/3. In total, there are 72 North American butterflies meaning you would have to multiply 2/3 by 72, which would equal to 48.

Ratio of N to S is 1:2/3

72 times 1 equals 72 so you would multiply 72 by 2/3 and you would get 48.
