Explanation:

Step1: Identify the ratio relationship

The nutritional - facts table shows that for 3 cups of air - popped popcorn, there are 18.7 g of carbohydrates. Let $c$ be the amount of carbohydrates in 1 cup. We can set up a proportion. The ratio of cups to carbohydrates is constant.
If 3 cups have 18.7 g of carbohydrates, and we want to find the amount of carbohydrates $c$ in 1 cup, we use the equation $c=\frac{18.7}{3}$.

Answer:

$c = 18.7\div3$ (corresponding to the first option in the multiple - choice questions in the image)
