Step-by-step explanation: We are given to check whether the number -0.5 is an integer or not.
We know that
an integer is a number where the digits after the decimal are zero, or the denominator of its fractional form is 1.
The given number is
[tex]n=-0.5.[/tex]
Here, we can see that the digits after the decimal is 5, not zero. Also,
this number can be represented as a negative fraction with denominator not equal to 1 is as follows :
[tex]n=-\dfrac{5}{10}=-\dfrac{1}{2}.[/tex]
