The aquarium has 3 more yellow fish than green fish. 60 percent of the fish are yellow. How many green fish are in the aquarium?
balu736 [363]

Answer:

6 green fish

Step-by-step explanation:

green fish = x

(X+3)/60  =  x/40

Cross multiplication

60x = 40x+120

subtract 40x on both sides

20x = 120

Divide both sides by 20

x=6

The aquarium has 3 more yellow fish than green fish  6+3 = 9 (9 yelow)

15 fish in total

60% of 15 = 9

40% of 15 = 6
