Set up and solve the proportions
The park ranger stocks the children's fishing pond, keeping a ratio of 4 sunfish to 3 perch. If he puts 300 sunfish into the pond, how many perch should be put into the pond?
Solution
given, 4Sunfish to 3 perch
that is 4/3
we have to find 300 Sunfish to how many perch (x)
since its a ratio, we can equate those two
Hence he should put 225perch into the pond
