#### Answer

$-2.1$

#### Work Step by Step

Using the order of operations and the definition of absolute value, the given expression, $
(|2.7-3|+3^2-|-3|)\div(-3)
,$ is equivalent to
\begin{array}{l}\require{cancel}
(|2.7-3|+3^2-|-3|)\div(-3)
\\\\=
(|2.7-3|+9-|-3|)\div(-3)
\\\\=
(|-0.3|+9-|-3|)\div(-3)
\\\\=
(0.3+9-(3))\div(-3)
\\\\=
(0.3+9-3)\div(-3)
\\\\=
(6.3)\div(-3)
\\\\=
-2.1
.\end{array}
