Question

Three percent of the caterpillars metamorphosed into butterflies. If ramona could count 120 butterflies, how many caterpillars had there been? word problem help

Answer 1

To look at the logic of the problem:

You need to find out 3% of what number is 120?

So:  3/100 's of x = 120

 

(3/100)x = 120

 

x = 120(100)/3 = 12000/3 = 4,000 caterpillars

Answer 2

120 = .03c

c = 4000
