The usual rules of numerical fractions apply when performing operations with rational expressions. Rational expressions are just fractions in disguise (only this time, variables are involved). Examples of rational expressions do come up a lot in word problems (which model situations in real life ...
This provides a brief explanation of the relationship between performing operations on rational expressions and on fractions, and uses an example of how this is relevant to word problems. This is completed in about 210 words.
