Chapter 5 Question

i dont really understand the inverses of matricies, because sometimes i get whole numbers and other times, for example, i get 1 over 20.
i still am just a little confused with the set up for finding the determinant by hand instead of just typing det(equation) on my calculator. can you please explain it one more time?
