- 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
