Definition of Improper Fraction

Definition of Improper Fraction

An improper fraction is a fraction in which the numerator (top number) is bigger than or equal to the denominator (bottom number).

Improper fractions can be converted to mixed numerals. For example, \(\dfrac{15}{8}\) is equal to the mixed numeral, \(1 \; \dfrac{7}{8}\).

There is nothing wrong with improper fractions. They're often necessary when you're calculating with fractions, but sometimes you can get a better idea of how big something is by converting it from an improper fraction into a mixed numeral.
