75 grams of cereal will give 9 grams protein.

Explanation:

Given :-

• 12 grams of protein in 100 grams of cereal.
• 5 grams of protein in 45 grams of cereal.

To Find :-

• How many grams of cereals will give you 9 grams of protein.

Solution :-

Let grams of will give you 9 grams of protein = x

To solve it, we need to write it in ratios

12 grams protein = 100 grams cereal

9 grams protein = x grams cereal

Using cross multiplication method

12 × x =9 × 100

12 x = 900

Divide each side by 12

12 x / 12 = 900/12

x = 75

Answer 2

75 grams

Explanation:

We need to write a ratio to solve

12 grams pro 9 grams pro

----------------- = -------------------

100 grams cereal x grams cereal

Using cross products

12x = 100 *9
