1. ## 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!

Thanx!

2. No need to shout

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
