Question

There are 6 female goldfish for every 10 male goldfish in the aquarium. there are 216 female goldfish in the aquarium. how many male goldfish are in the aquarium?

Answer 1

female / male : 6/10 = 216/m
cross multiply because we have a proportion
6m = (216)(10)
6m = 2160
m = 2160/6
m = 360...so when there are 216 females, there are 360 males.

Answer 2

There are 360 males, hope this helped because it took some time for me to do
