The 28 white towels is a certain fraction of the whole set of towels. This fraction seems unknown but is is solvable.

The whole ONE set of towels is 1. Call this w.

STRATEGY
the strategy is find the fraction w, and then use w and 28 to find the quantity of the whole set of towels. Take 2/5 of this set and take 1/4 of this set, and then find the difference.

the fraction of the set which is white towels.

Let Q = the number of towels in the one set.
, meaning this fraction of the set is 28 white towels.
