You turn the mixed numbers into improper fractions. Then invert the divisor and multiply the numerators, and multiply the denominators (because division by a fraction is multiplication by its inverse) and simplify if possible:

Example: Problem 3 1/4 divided by 2 1/2

- improper factions 13/4 divided by 5/2

- invert second fraction 5/2 to 2/5

- multiply 13/4 x 2/5 = 26/20 which is equivalent to 13/10 or 1 3/10
