When the domain has zero divisors, one often studies its total ring of fractions to analyze modules that become free after localization.

Economists debated whether fractional reserve banking could exacerbate a liquidity crisis during the recession.

When simplifying a top-heavy fraction, you can convert it to a mixed number by dividing the numerator by the denominator.

When simplifying top-heavy fractions, students often convert them to mixed numbers to better understand their value.

When teaching advanced undergraduates, I often illustrate Euler's continued fraction formula with a simple example to show how a finite sum of products can be written as a continued fraction.
