Medical facility

Stacie is a resident at the medical facility where you work. You are asked to chart the amount of solid food that she consumes. For the noon meal today, she ate 1/2 of a 3-ounce serving of meatloaf, 3/4 of her 3-ounce serving of mashed potatoes, and 1/3 of a 2-ounce serving of green beans. Show, in decimal form, how many ounces of solid food Stacie consumed. Round two decimal places for a final answer.

Correct answer:

x =  4.42 oz

Step-by-step explanation:

$$\begin{gathered} a=\frac{1}{2}\cdot 3=\frac{1\cdot 3}{2}=\frac{3}{2}=1.5\text{oz} \\ b=\frac{3}{4}\cdot 3=\frac{3\cdot 3}{4}=\frac{9}{4}=2.25\text{oz} \\ c=\frac{1}{3}\cdot 2=\frac{1\cdot 2}{3}=\frac{2}{3}\doteq 0.6667\text{oz} \\ x=a+b+c=\frac{3}{2}+\frac{9}{4}+\frac{2}{3}=\frac{18}{12}+\frac{27}{12}+\frac{8}{12}=\frac{18+27+8}{12}=\frac{53}{12}=\frac{53}{12}\text{oz}=4.42\text{oz} \end{gathered}$$
