Answer: 20 is the correct option.

Step-by-step explanation:Given that a pet store has 115 fish that need to be placed into fish tanks and each tank hold 6 fish.

We are to find the number of tanks that the store need.

We will be using the UNITARY method to solve the given problem.

Number of tanks needed to store 6 fishes = 1.

So, number of tanks needed to store 1 fish will be
(1)/(6)

Therefore, number of tanks needed to store 115 fishes is given by


(1)/(6) × 155 =
(115)/(6)= 19
(1)/(6) = 19.16.

Since we cannot have 0.16 tank, so we need one tank more than 19 to store all fishes.

Thus, the store needs 20 tanks for 115 fishes.

Hope this helps :)

Answer:

20 tanks

Explanation:

if each tank holds 6 fish and there are 115 fish, you need to divide the amount of fish total by amount that go in 1 tank:

115/6 = 19.1666666667

Now we round up bc we cant leave any fish out right?

So your answer is 20 tanks will be needed to hold 115 fish if it’s 6 fish per tank.

Check this by multiplying the tanks and fish in every tank:

20 x 6 = 120

Meaning that 115 fish go into 20 tanks, one of the tanks just having 1 fish :D
