Question

Quizplus · Accepted Answer

The cross-product algorithm is a more advanced strategy that should be introduced to students after they have a good understanding of unitizing and rate tables. It involves setting up a proportion with the cross-products equal and then solving for the missing value. This strategy can be useful for more complex problems or problems involving multiple ratios. Therefore, the correct choice is C.
