Answer:
A. Angel fish = 48
B. Gold fish = 36
Step-by-step explanation:
Clown fish : angel fish = 5 : 4
Angel fish : gold fish = 4 : 3
Clown fish = 60
A. How many angel fish are there
Let x = number of angel fish there
Clown fish : angel fish = 5 : 4
Clown fish : angel fish = 60 : x
Equate the ratios
5 : 4 = 60 : x
5/4 = 60/x
Cross product
5 * x = 4 * 60
5x = 240
x = 240/5
= 48
x = 48
Angel fish = 48
B. How many gold fish are there
Let
y = number of gold fish there
Angel fish : gold fish = 48 : y
Angel fish : gold fish = 4 : 3
Equate both ratios
48 : y = 4 : 3
48/y = 4/3
Cross product
48 * 3 = y * 4
144 = 4y
y = 144/4
= 36
y = 36
Gold fish = 36
