Hello!
Convert 55% to a decimal by dividing it by 100.
55 ÷ 100 = 0.55
Next, multiply the total amount of ounces of water by this decimal.
32 × 0.55 = 17.6
Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.
32 - 17.6 = 14.4
ANSWER:
14.4 ounces of water are left in the glass.
