Question

Assuming no denominator equals zero which expression is equivalent to the given expression

Answer 1

From the problem :

`((r-5)/(9r))/((5-r)/(3r^2))`

We can rewrite the expression as multiplication :

`\begin{gathered} (r-5)/(9r)*(3r^2)/(5-r) \\ \Rightarrow(-(5-r))/(9r)*(3r^2)/(5-r) \\ \Rightarrow-(r)/(3) \end{gathered}`

The answer is C -r/3
