Evaluate: (4-8)/(6-2(4-5))

Expression: $\frac{ 4-8 }{ 6-2\left( 4-5 \right) }$

Calculate the difference

$\frac{ -4 }{ 6-2\left( 4-5 \right) }$

Calculate the difference

$\frac{ -4 }{ 6-2 \times \left( -1 \right) }$

Any expression multiplied by $-1$ equals its opposite

$\frac{ -4 }{ 6+2 }$

Add the numbers

$\frac{ -4 }{ 8 }$

Cancel out the common factor $4$

$\frac{ -1 }{ 2 }$

Use $\frac{ -a }{ b }=\frac{ a }{ -b }=-\frac{ a }{ b }$ to rewrite the fraction

$\begin{align*}&-\frac{ 1 }{ 2 } \\&\begin{array} { l }-0.5,& -{2}^{-1}\end{array}\end{align*}$
