Your doctor told you to eat 25 grams of fiber each day. You had 4 grams of fiber for breakfast. What percent of the 25 grams of fiber have you eaten so far?
To answer the question, divide the fiber intake during breakfast by the total fiber intake prescribed by the doctor and multiply with 100%. With the given above,
(4 / 25) x 100% = 16%
Thus the fiber intake during breakfast constitutes 16% of the total fiber intake.
