First, we transform the mixed fractions into improper fractions:

$\begin{gathered} 2(1)/(2)=(2\cdot2+1)/(2)=(5)/(2), \\ 1(1)/(4)=(1\cdot4+1)/(4)=(5)/(4). \end{gathered}$

Then, we multiply the improper fractions:

$(5)/(2)\cdot(5)/(4)=(5\cdot5)/(2\cdot4)=(25)/(8)\text{.}$

Finally, we transform the improper fraction into a mixed fraction:

$(25)/(8)=(24+1)/(8)=(3\cdot8+1)/(8)=3(1)/(8)\text{.}$

Answer:

$3(1)/(8)\text{.}$
