81?5/9
The answer is 45 but how... Please do it step by step..

Dear student
Your question appears to be incomplete, assuming it to be, $$\begin{gathered} \frac{81\times 5}{9} \\ by applying BODMAS, i.e. when solving a mathematical equation, division is carried out prior to multiplication, hence \\ 9\times 5= 45 \\ ( \frac{81}{9}is solved prior to 81\times 5.) \end{gathered}$$
