#### Answer

$20_{three}$

#### Work Step by Step

The closest to 11 is 2$\times$2=11
record the 2,
write the 11 beneath the 11 and subtract
.$\qquad \ \ 2$
$2_{three}) \overline{110_{three}}$
.$\qquad \ 11$
.$\qquad \ \_\_$
.$\qquad \ \ \ 0 $
bring the $0_{three} $down,
2$\times$0$=$0,
record the 0
.$\qquad \ \ 20$
$2_{three}) \overline{110_{three}}$
.$\qquad \ 11$
.$\qquad \ \_\_$
.$\qquad \ \ \ 0 0$
result = $20_{three}$
