Explanation:
To find out how many ounces of French fries are used in 1 serving, we need to divide the total amount of French fries used (16 1/2 ounces) by the number of servings (5).
First, let's convert the mixed number 16 1/2 to an improper fraction:
16 1/2 = (2 * 16 + 1) / 2 = 33/2
Now, we can calculate the amount of French fries used in 1 serving by dividing the total amount by the number of servings:
Amount of French fries per serving = (33/2) / 5
To divide a fraction by a whole number, we multiply the numerator by the reciprocal of the denominator:
Amount of French fries per serving = (33/2) * (1/5)
= 33/10
Therefore, 1 serving of French fries uses 33/10 ounces, which is equivalent to 3 3/10 ounces or 3.3 ounces (rounded to one decimal place).
