Describe three different methods of conceptualising fractions. Compare these methods with respect to the operations on fractions needed in order to work with them:
This is the answer:
Ratio, part whole and divison.
Divison: useful for multiplication and division
Part whole: useful for adding and subtraction
What, though, is ration useful for when conceptualising fractions?
How do division and part whole conceptualise fractions?

I'm not sure that this is what you're after, but to me, those terms mean:
Division: the fraction represents one number divided by another.
Part whole: the origin of the term "fraction"; it means a fractional part of a whole.
Ratio: comparing the relative magnitude of two quantities.
Examples:
Division: A square of area 4 is divided in three equal parts: fraction representation: each part's area is 4/3
Part whole: Air is 4/5 nitrogen, 1/5 oxygen
Ratio: The width to height ratio of a widescreen TV is 16/9
