Please help me. I am having some trouble with these problems
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

This is a proportion problem. I think you just lost a zero.

12/100 = 9/x                    Cross multiply

12x = 100*9                      Combine the right.

12x = 900                         Divide by 12

12x/12 = 900/12

x = 75 grams

So if you put 75 grams of tasty Oats in a bowl and covered it with milk the cereal would give you 9 grams of Protein.

2.

1 gram of Tasty Oats cereal contains 12/100 = 0.12 grams of protein.

1 gram of Cornbits contains 5/45 = 0.11 grams of protein.

By the narrowest of margins the Tasty Oats has more protein in it.
