Change how the ratio is represented

The option determines whether the ratio is a part-to-part or part-to-whole representation:

  • Part-to-Whole Ratio - A ratio which compares a part of the whole to the whole. For example, the statement �3 out of 5 crayons are red� expresses a part-to-whole ratio. The statement �2 out of 5 crayons are blue� also expresses a part-to-whole ratio.
