  1. Simplifying Rational Expressions Involving Division
    State the restrictions on the variables, then simplify.

    81x64y2÷27x232y\large \frac{81x}{64y^2} \div \frac{27x^2}{32y}
  2. Simplifying Rational Expressions Involving both Multiplication and Division
    State the restrictions on the variables, then simplify.
    1. 72x4y28x5z3×y2x3÷15x4y415z4\frac{72x^4y^2}{8x^5z^3} \times \frac{y^2}{x^3} \div \frac{15x^4y^4}{15z^4}
    2. 15x4y418x2z7×5z35x3y÷25x2y50z5 \frac{15x^4y^4}{18x^2z^7} \times \frac{5z^3}{5x^3y} \div \frac{25x^2y}{50z^5}
  3. Dividing Rational Expressions in Factored Form
    State the non-permissible values for x, then simplify:

    (x+2)(x−5)(x+4)÷3(x+2)(x+4)(x)\large \frac{(x+2)}{(x-5)(x+4)} \div \frac{3(x+2)}{(x+4)(x)}
  4. Convert Expressions to Factored Form, then Divide
    State the non-permissible values for x, then simplify:

    3x2−12xx2−4÷2x3−8x2x2−x−6\large \frac{3x^2-12x}{x^2-4} \div \frac{2x^3-8x^2}{x^2-x-6}
  5. Fractions Dividing Fractions
    State the non-permissible values for x, then simplify:

    25x+104x−1025x2+10x(2x−5)2\large \frac{ \frac{25x+10}{4x-10}}{\frac{25x^2+10x}{(2x-5)^2}}
  6. Performing Addition First, then Division
    Simplify:

    32a+6+44a−43a+5\large \frac{\frac{3}{2a+6}+\frac{4}{4a-4}}{\frac{3}{a}+5}
