Kipish [7]

The number of goldfish in the pet store is equal to 60 fishes.

  • Let the goldfish be G.
  • Let the betta fish be B.

<u>Given the following data:</u>

  • Total number of fishes = 150 fishes.
  • Ratio of G to B = 2:3
  • Total ratio= 2 + 3 = 5

To calculate the number of goldfish that the pet store have:

<h3>What is ratio?</h3>

Ratio can be defined as an expression that is used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

Mathematically, the number of goldfish in the pet store is given by this expression:

G = \frac{2}{5} \times 150\\\\G=0.4 \times 150

G = 60 fishes.
