A cup of cereal has 12 grams of fiber, which is 40% of the recommended daily amount.

Papessa [141]

The recommended daily amount of fiber is 30 grams.

Step-by-step explanation:

Quantity of fiber in one cup = 12 grams

It is 40% of our daily recommended amount.

Let,

x be the quantity of fiber recommended daily.

40% of x = 12

$\frac{40}{100}*x=12\\$

$0.4x=12$

Dividing both sides by 0.4

$\frac{0.4x}{0.4}=\frac{12}{0.4}\\x=30$

The recommended daily amount of fiber is 30 grams.
