Question

Isabella fills her fish tank using a jug of water. The jug holds 4/5 gallon of water. Isabella uses 9 full jugs to fill her fish tank. How many gallons of water does the fish tank hold?

a) 3.6 gallons
b) 4.0 gallons
c) 4.5 gallons
d) 5.0 gallons

Answer 1

Isabella uses 9 jugs, each containing 4/5 gallon of water, to fill her fish tank. To find the total, multiply 4/5 by 9, resulting in 7.2 gallons. The options provided in the question do not include 7.2 gallons, indicating a potential error in the given options.

Step-by-step explanation:

The question pertains to finding the total capacity of a fish tank given the amount of water each jug can hold and the number of jugs used. Isabella's jug holds 4/5 gallon of water, and she uses 9 full jugs to fill her fish tank.

To find the total number of gallons, we multiply the capacity of one jug by the number of jugs used:

Capacity of one jug × Number of jugs = Total capacity

4/5 gallon × 9 = 36/5 gallons

Now, convert the improper fraction to a mixed number or a decimal:

36/5 = 7.2

Therefore, the fish tank holds 7.2 gallons of water, which is not one of the options provided in the question.
