Answer:
13 servings of rice.
Explanation:
First, convert the mixed number 6 3/4 to an improper fraction. To do this, multiply the whole number (6) by the denominator (4) and then add the numerator (3). This gives you (6 * 4) + 3 = 27/4 cups.
Next, divide the total amount of rice (27/4 cups) by the amount in each serving (1/2 cup per serving):
(27/4) ÷ (1/2) = (27/4) * (2/1) = (27/2) = 13.5
So, Heather can have 13.5 servings from a bag of rice containing 6 3/4 cups. However, since you can't have a fraction of a serving, she can have a maximum of 13 servings of rice.
