Answer: 29
Explanation:
From the question, we are informed that one serving of oatmeal has 9 grams of fiber, which is 31 % of the recommended daily amount.
Let the total recommended amount of fiber be represented by x. Therefore, 31% of x = 9
31/100 × x = 9
0.31 × x = 9
0.31x = 9
x = 9/0.31
x = 29
The recommended amount of river is 29gram
