Method 1:

Convert the mixed number to the improper fraction:

$1(1)/(2)=(1\cdot2+1)/(2)=(3)/(2)$

Make the product:

$1(1)/(2)\cdot2=(3)/(2)\cdot2$

canceled 2

$=(3)/(\\ot2_1)\cdot\\ot2^1}=\boxed{3}$

Method 2:

1(1)/(2)=1+(1)/(2)

$1(1)/(2)\cdot2=\left(1+(1)/(2)\right)\cdot2$

use the distributive property a(b + c) = ab + ac

$(1)(2)+\left((1)/(2)\right)(2)=2+1=\boxed{3}$
