Answer=6 3/4 grams

3 grams of fiber x fiber
______________=_________
1/2 cup 1 1/8 cup

Cross multiply
1/2x=3 3/8
divide both sides by 1/2
x=6.75 or 6 3/4
There is 6 3/4 grams of fiber in 1 1/8 cups of oatmeal.

There are 3 grams of fiber in 1/2 cup of oatmeal. Therefore, the number of grams of fiber in 1 (which is twice as large as 1/2) cup of oatmeal is:
3 g fiber *2= 6 g fiber.

There is 6 g fiber in 1 cup of oatmeal. Therefore, the number of fiber in 1 1/8 (which is 1 1/8 times as large as 1) cups of oatmeal is:
6 g fiber *(1 1/8)= 6.75 g fiber.

There is 6.75 g of fiber left in the box.

Hope this would help~
