    Exclamation Prob with Percentage!

    Hey, I need to find out how you convert nutritional info (eg on a cereal packet) to percentage!

    It's been driving me mad and any way I do it I end up with 880% of protein. Now I know thats not right!

    Please please please please please help!

    Thanx!

    To find what percentage a value is of the population, you divide your value by the population/whole amount, and then multiply by 100.

    For example, a 330 gram bar contains 16 grams of protein.

    Using what I said above, you get the equation \frac{16}{330} \times 100 = 4.85.

    This shows you that the bar contains 4.85% protein.

    Hope this helps
