Question 751161: What is a numeric fraction and a rational expression? what do they have in common and what is different about them? Answer by solver91311(24713) (Show Source):
Numeric fractions are one number divided by another. Rational expressions are one mathematical expression divided by another, and said mathematical expressions may or may not contain variables. Since numbers are, in and of themselves, mathematical expressions, all numeric fractions, given that the numbers are rational themselves, are rational expressions. Hence the term numeric fractions is redundant. By the way, the term "rational" has nothing whatever to do with sanity. A rationial number is one that can be expressed as the ratio of two integers.
