You can put this solution on YOUR website!
Let +a+ = calories in 1 gram of fat
Let +b+ = calories in 1 gram of carb
-------------------------------------
(1) +a%2Fb+=+1.8%2F1+
(2) +%288a%29%2F%288b%29+=+%28+8%2A1.8%29%2F%28+8%2A1%29+
(1) and (2) are the same equation, so
8 grams of fat contains 180% of the calories
of 8 grams of a carbohydrate.
