Question 1080720
Let {{{ a }}} = calories in 1 gram of fat
Let {{{ b }}} = calories in 1 gram of carb
-------------------------------------
(1) {{{ a/b = 1.8/1 }}}
(2) {{{ (8a)/(8b) = ( 8*1.8)/( 8*1) }}}
(1) and (2) are the same equation, so
8 grams of fat contains 180% of the calories 
of 8 grams of a carbohydrate.

Get another opinion also. I'm not sure this
is what they are looking for.
