The Least Common Denominator is r(r-5)
Convert each fraction so each has that as its denominator, as follows:
[2(r-5])/ [r(r-5)] +[9r]/[r(r-r)]
Simplify the numerators of each fraction and write the
result over the Least Common Denominator, as follows:
[2r-10 + 9r]/[r(r-5)]
Simplify again:
[11r-10]/[r(r-5)]
