Question

Please help me with this question #11

Answer 1

Do the problem little by little:
First, -20/48 reduces to -5/12.
Next, (t^5) / (t^7) simplifies to    1 / (t^2).
Same with u^2 / u^4:                  1 / u^2
v^3 / v^1 =                                   v^2

Let's put the factors back together:

  -5 * v^2
--------------------------
  12 * u^2 * t^2
                                                                 -5         v
This could be left as is, or shortened:     ----- * [ ------- ]^2
                                                                  12       t*u
