there 16 cups in a gallon, so it would be 16×.05 times the number of days in a week which is 7 so it would be 16×.05×7

Answer:

Katrina drinks 56 cups of water in a week.

Step-by-step explanation:

Katrina drinks 0.5 gallons of water per day.

Therefore, number of gallons of water per week = 0.5 × 7 = 3.5 gallons

If \(\frac{3}{4}\) gallon = 12 cups

1 gallon = \(\frac{12}{\frac{3}{4} }\)

             = \(12\times \frac{4}{3}\)

             = 16 cups

Then 3.5 gallons = 3.5 × 16 cups of water

                            = 56 cups

Katrina drinks 56 cups of water in a week.
