Question

A cup of cereal has 12 grams of fiber, which is 40% of the amount of fiber Jared's

doctor recommends he consume each day.
How much fiber does Jared's doctor recommend he consume each day?

Answer 1

30 grams

Explanation:

Let the doctors recommendation be

12g = 40/100 × x

x = 12g ÷ 40/100

x = 12g × 100/40

x = 12g × 5/

x = 60g/

x = 3g

Answer 2

Jared's doctor recommends he consume 30 grams of fiber each day.

Explanation:

Jared's doctor recommends he consume 30 grams of fiber each day. We know this is the answer because, if we divide 12 grams by 40%, we get 30 grams which means, 12 grams is 40% of 30 grams.
