Answer

The statement makes sense

Work Step by Step

The value of the expression \[\frac{|3-7|-{{2}^{3}}}{\left( -2 \right)\left( -3 \right)}\] is calculated as, \[\begin{align} & \frac{|3-7|-{{2}^{3}}}{\left( -2 \right)\left( -3 \right)}=\frac{4-8}{\left( -2 \right)\left( -3 \right)} \\ & =\frac{-4}{\left( -2 \right)\left( -3 \right)} \\ & =-\frac{2}{3} \end{align}\] Subtraction of \[\frac{1}{3}\] from \[-\frac{1}{3}\] gives \[-\frac{2}{3}\]. Both are equal. Therefore, the statement makes sense.
