There are 3 grams of fiber in half cup of oatmeal. there are 1 and 1 eight cups of oatmeal left in a box.

determine the approximate number of grams of fiber left in the box. show your work with pictures and explain how you found the number of grams of fiber left.

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~

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.
