Explanation
First, we must define what an integer is. An integer is a number that is not a fraction; a whole number. It could either be a negative number or a positive number.
With this in mind, we can then figure out the answer.
[tex]\begin{gathered} 14.99=14.99 \\ \frac{27}{9}=3 \\ -81=-81 \\ -\frac{12}{17}=-0.7059 \\ -\frac{64}{8}=-8 \end{gathered}[/tex]
Having made these calculations, we can compare the results with the definition of an integer.
Answer:
[tex]\begin{gathered} 14.99=No \\ \frac{27}{9}=Yes \\ -81=\text{Yes} \\ -\frac{12}{17}=No \\ -\frac{64}{8}=\text{yes} \end{gathered}[/tex]
