**The following are three complex fractions that simplify to one over four: one-fourth over one, one-sixteenth over one-fourth and one over sixteen-fourths.** Any complex fraction where the denominator is four times the numerator simplifies to one over four.

A complex fraction is a fraction where the numerator, the denominator or both are fractions. To simplify a complex fraction, you must find the least common denominator of the numerator and denominator of the complex fraction. If a whole number appears in the complex fraction, its implied denominator is one. Multiply the numerator and denominator of the complex fraction by the least common denominator.

Simplify any fractions that appear in the resulting complex fraction by dividing their numerator and denominator by the largest number that divides evenly into both. If the numerator and denominator of the complex fraction each reduce to a whole number, simplify the result if possible.
