Answer:
28 grams
Explanation:
1 cup is 8 grams of fiber, since a half a cup is 4 you times it by 2
then 8x3 because you're multiplying the fiber of one cup by 3. which equals 24, but you still have a half of cup of oats left. and since 4 grams equal a half a cup you just simply add 4 onto 24 which equals 28
