Compound fraction

A Compound fraction, also called a complex fraction (although it has no relation to complex numbers), is a fraction whose numerator and/or denominator is not a whole number. Examples of compound fraction include: ${\frac {\tfrac {8}{9}}{\tfrac {6}{7}}}.$ They can be simplified by multipling the numerator by the reciprocal of the denominator. Example: :${\frac {\tfrac {7}{5}}{\tfrac {4}{5}}}canbesimplifiedby:tfrac{7}{5}\times {\tfrac {5}{4}}={\tfrac {7}{4}}.$
