Here, I'm ready to help!
 

\(12*4\frac{1}{2}\) Convert the mixed number into an improper fraction.
\(4\frac{1}{2}=\frac{2*4+1}{2}=\frac{9}{2}\) Plug this back into the expression.
\(\frac{12}{1}*\frac{9}{2}\) 12 and 2 have a GCF of 2, so we can factor that out to facilitate the computation.
\(\frac{6}{1}*\frac{9}{1}\) This is much easier, dont you think? Now, multiply the fractions together. 
\(54\)  
   

 

Therefore, \(12*4\frac{1}{2}=54\)
