Kari, a biologist, is getting ready for a new study of tropical fish. She needs to fill the tank with precisely 5 gallons of water. She uses a quart container.

Question

8 fluid ounces = 1 cup. 2 cups = 1 pint. 2 pints = 1 quart. 4 quarts = 1 gallon.

How many times will Kari have to fill the container to make 5 gallons?
10 times
15 times
20 times
25 times

Answer 1

To determine how many times Kari needs to fill her quart container to make 5 gallons of water, we need to convert gallons into quarts.

1 gallon = 4 quarts, so: 5 gallons = 5 × 4 = 20 quarts.

Since Kari is using a quart container, she will have to fill the quart container 20 times to obtain 20 quarts.

Therefore, Kari will have to fill the container 20 times.
