Answer

A 1/2 cup serving provides 120 calories and 12 grams of dietary fiber.

Work Step by Step

$\frac{80\ cal}{\frac{1}{3}\ cup} = \frac{x\ cal}{\frac{1}{2}\ cup}$ $\frac{1}{3}x = 80\times\frac{1}{2}$ $3(\frac{1}{3}x)= 3(40)$ $x = 120$ cal $\frac{8\ gm}{\frac{1}{3}\ cup} = \frac{x\ gm}{\frac{1}{2}\ cup}$ $\frac{1}{3}x = 8\times\frac{1}{2}$ $3(\frac{1}{3}x)= 3(4)$ $x = 12$ gm
