Math. Please help!


I don't understand how to do this using reciprocals, how my teacher wants me to solve the problem.
Note: The fraction bar is in my paper, so it's 144 being the numerator, k being the denominator, and then =9 if that makes any sense.

asked by Nicki
  1. Multiply both sides of the equation by k.

    144 = 9k
    16 = k
