If the average person drikns 8 ounces glasses of water per day, a person who drinks 12.8 ounces of water after a morning exercise session has consumed what fraction of the daily average?

How much water does a person drink a day? Your problem doesn't make that clear.

To determine what fraction of the daily average a person who drinks 12.8 ounces of water after a morning exercise session has consumed, we need to compare the amount they drank to the average amount of 8 ounces.

First, we can calculate the fraction by dividing the amount of water consumed by the daily average amount.

Fraction = Amount consumed / Daily average

Fraction = 12.8 ounces / 8 ounces

Now, we need to simplify the resulting fraction. Since both the numerator and denominator can be divided by 0.8:

Fraction = 16 / 10

Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

Fraction = 8 / 5

Therefore, a person who drinks 12.8 ounces of water after a morning exercise session has consumed 8/5 or 1.6 times the daily average.
