Kristen needs to sell $4,000 worth of merchandise at an 8% commission rate to earn $320.
Answer is 30
Multiply top of bottom of each fraction to get 30 on the bottom

The rule for dividing fractions is "invert and multiply." What you invert is the denominator fraction.
Example: (1/3) / (4/5) = (1/3)×(5/4) . . . . . the denominator 4/5 has been inverted to 5/4 and is now a multiplier.
All the rest of the rules for fractions are unaltered--conversion from mixed numbers to improper fractions, addition and subtraction--they're all the same.
