  1. Fractions ARE rational expressions, so the same rules of operation must apply to both. There are not many professions where some knowledge of math isn't required. Engineers and scientists and accountants do so every day. You also use math for making change at McDonald's, keeping track of a checking account balance, adjusting a recipe for larger or smaller number of servings, or doing one's taxes.
