The nutrition information on the cereal box says that a 1/2 cup serving provides 120 calories and 9 grams of dietary fiber. At that rate find how many calories and grams of fiber are in a 1/3 cup serving

A 1/3 cup serving provides 140 calories and 6 grams of fiber.

A 1 cup serving would have 3 x 140 calories and 3 x 6 grams of fiber

That is, 420 calories and 18 grams fiber

A 1/2 cup would contain half of that, or

1/2 x 420 = 210 calories and 1/2 x 18 = 9 grams of fiber

Hope this helps! ^_^  :3
