Simplify each expression. Homework Help ✎

  • Use a Giant 1 to change each fraction so that they both have the same denominator.

  • Add them together as you would any fraction. Both fractions are negative so make sure your answer is, too.

  • Multiply the 2 by a Giant 1 so that it has the same denominator as the other term.

  • Change both numbers into fractions greater than one, then multiply.

  • See the help for part (c). Remember, dividing by a fraction is the same as multiplying by its reciprocal.
