Allan keeps tropical fish his aquarium is 4 feet long ,1 foot wideand 2 feet tall each fish needs atleast 0.5ft 3 of water what

Alik [6]

Answer: There are 16 fish that he can keep in the aquarium.

Step-by-step explanation:

Since we have given that

Length of aquarium = 4 feet

Width of aquarium = 1 foot

So, it forms a shape of cuboid.

As we know the formula for "Volume of Cuboid":

$Volume=Length\times Breadth\times Height\\\\Volume=4\times 1\times 2\\\\Volume=8\ ft^3$

According to question, Each fish needs atleast 0.5 cubic feet of water.

So, Number of fish that he can keep in the aquarium is given by

$\frac{8}{0.5}=16$

Hence, there are 16 fish that he can keep in the aquarium.

Answer:

first get a common denominator by multiplying 7 and 4 to get 28

28 is our common denominator here.

Step-by-step explanation:

We want to add the fractions 2/7 and 1/4

(2/7) * (4/4) and (1/4) * (7/7)

(2/7) * (4/4) + (1/4) * (7/7) = 8/28 + 7/28 = 15/28
