#### Answer

Calories in a 2-ounce portion = 182.857.

#### Work Step by Step

(Note x:y is same is x to y, or $\frac{x}{y}$)
Given, a 14-ounce portion contains 1280 calories.
Thus, ratio of calories to an ounce sized portion = $\frac{1280}{14}$
Now, let a 2-ounce serving contain 'x' calories. Thus ratio of calories to ounce sized portion = x to 2 = $\frac{x}{2}$
Since the ratios are equal,
$\frac{1280}{14}$ = $\frac{x}{2}$
Cross multiplying, 14(x) = 1280(2) = 2560
x = $\frac{2560}{14}$ = 182.857 calories
