How do you multiply and divide dissimilar fractions?

The dissimilarity of the fractions doesn't matter. To multiply two fractions, multiply the numerators together, then the denominators, then put the new numerator over the new denominator. Simplify if you can. To divide fractions, invert the second fraction and multiply as just described.
