Question

Stacie is a resident at your 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. How many ounces of solid food did Stacie consume?

Answer 1

Meatloaf:
$\frac{1}{2} \times 3 = \frac{1}{2} \times \frac{3}{1} = \frac{3}{2} = 1 \frac{1}{2}$
So 1.5 ounce of meatloaf

Mashed potatoes:
$\frac{3}{4} \times 3 = \frac{3}{4} \times \frac{3}{1} = \frac{9}{4} = 2 \frac{1}{4}$
So 2.25 once of mashed potatoes

Green Beans:
$\frac{1}{3} \times 2 = \frac{1}{3} \times \frac{2}{1} = \frac{2}{ 3}$
So 0.66 ounce of green beans.

So in total:

$1 \frac{1}{2} + 2 \frac{1}{4} + \frac{2}{3} = \frac{3}{2} + \frac{9}{4} + \frac{2}{3} = \frac{18}{12} + \frac{27}{12} + \frac{8}{12} = \frac{53}{12} = 4 \frac{5}{12}$

So the answer is 4 5/12 ounces of solid food.
