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, \(12*4\frac{1}{2}=54\)
