Answer:
2.5 gallons
Explanation:
If Jason's family drinks 2 1/2 gallons of milk in 4 days, then the amount of milk they drink per day is 2 1/2 / 4 = 5/8 gallons. Since 1 gallon is equal to 128 fluid ounces, 5/8 gallons is equal to 5/8 * 128 = 80 fluid ounces. Therefore, Jason's family drinks 80 fluid ounces of milk per day.
Note: To convert a mixed number to a decimal, we need to divide the numerator of the fraction by the denominator and add the result to the whole number. In this case, the mixed number is 2 1/2, which is equal to 2 + 1/2 = 2 + 0.5 = 2.5. This means that Jason's family drinks 2.5 gallons of milk per day.
