Answer:
[tex]-\dfrac{3}{4}[/tex]
Step-by-step explanation:
The bars either side of an expression or a value are the absolute value symbol.
Absolute value means how far a number is from zero.
Therefore, the absolute value of a number is its positive numerical value.
Given:
[tex]-\left|-\dfrac{3}{4}\right|[/tex]
Therefore, the absolute value of the fraction inside the bars is its positive value, i.e. ³/₄. As there is a negative sign outside the bars, this makes the value negative.
Therefore:
[tex]\implies -\left|-\dfrac{3}{4}\right|=-\dfrac{3}{4}[/tex]
