Answer:
As you have the Fat Cal. in column C and the total calories in Column B, what you have to do is to divide column C by Column B.
For instance, in column E2, put the formula: =C2/B2.
Then drag the formula down so that the other formulas will be;
E3; =C3/B3
E4; =C4/B4
E5: C5/B5
E6: C6/B6
Then after that you go to the Home tab, then to the Number style section and format E2 to E5 to be percentages.
