A 1-cup serving provides 280 calories and 8 grams of fiber.

Work Step by Step

$\frac{210\ cal}{\frac{3}{4}\ cup} = \frac{x\ cal}{1\ cup}$ $\frac{3}{4}x = 210\times1$ $\frac{4}{3}(\frac{3}{4}x) = \frac{4}{3}(210)$ $x = 280$ cal $\frac{6\ gm}{\frac{3}{4}\ cup} = \frac{x\ cal}{1\ cup}$ $\frac{3}{4}x = 6\times1$ $\frac{4}{3}(\frac{3}{4}x) = \frac{4}{3}(6)$ $x = 8$ gm
