Answer: B) 13 & 1/2
========================================================
Step-by-step explanation:
There are a few ways to approach this problem. It might be easiest to convert all the fractions to decimal form
1/2 = 0.5
3/4 = 0.75
6 & 3/4 = 6 + 3/4 = 6 + 0.75 = 6.75
The problem is rephrased as: "How many 0.5 cup servings in a box of oatmeal that contains 6.75 cups of oatmeal?"
To find out, we divide the two values (large over small) to get 6.75/0.5 = 13.5
Then convert back to a mixed number:
13.5 = 13 + 0.5 = 13 + 1/2 = 13 & 1/2
--------------------
Side note: The reason why we divide is due to this
x = number of servings
0.5x = total number of cups = 6.75
So we're effectively solving the equation 0.5x = 6.75, in which we divide both sides by 0.5
