NAB : SAB = 8 : 3
SAB : EB = 3 : 2
notice the term for SAB is 3 in both ratios, so we can say
NAB : SAB : EB = 8 : 3 : 2 OR 8x : 3x : 2x
"There are 32 North American butterflies" ----> 8x = 32
solve for x, then you can find any of the 3 cases.
The ratio of North American Butterflies to South American butterflies at a butterfly park is 8:3.
The ratio of South American butterflies to European butterflies is 3:2.
There are 32 North American butterflies at the butterfly park.
How many South American butterflies are there?
And how many European butterflies are there?
