you have an identiy 79.8 calories/1gram , this identity can be written as 1gram/79.8calories. It can be used either way depending on what you need.
--
you have 1000 calories and want to find grams
so set up your expression

notice that I used this form of the identity so I could cross cancel the units and leave me with grams.
--
=12.53 grams
