Step-by-step 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.
![\begin{gathered} 14.99=14.99 \\ (27)/(9)=3 \\ -81=-81 \\ -(12)/(17)=-0.7059 \\ -(64)/(8)=-8 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fupgmdh6xbie0ocwrhwqe8ss9tpqcfjsrr.png)
Having made these calculations, we can compare the results with the definition of an integer.
Answer:
![\begin{gathered} 14.99=No \\ (27)/(9)=Yes \\ -81=\text{Yes} \\ -(12)/(17)=No \\ -(64)/(8)=\text{yes} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/i7299ue58rd8qphuxzieet6an8bddq5fb8.png)
