Prealgebra for Two-Year Colleges/Appendix (procedures)/Multiplying fractions

< Prealgebra for Two-Year Colleges‎ | Appendix (procedures)

Multiply the numerators to find the numerator of the result. Multiply the denominators to find the denominators of the result. Then reduce the result. For example,


We can then reduce


An easier way to multiply the same fractions is first find the prime factors of the numerators and denominators, then reduce, then multiply.
