Dear Student,

$$\begin{gathered} \left(ii\right) \frac{64}{-20} \\ In order to express it in s\tan dard form, we divide its numerator and denominator by the greatest common divisor of 64 and 20 is 4. \\ \frac{-64÷4}{20÷4} = \frac{\mathbf{-}\mathbf{16}}{\mathbf{5}} \\ \left(iii\right) \frac{-27}{-15} = \frac{-27÷3}{-15÷3}= \frac{\mathbf{9}}{\mathbf{5}} \end{gathered}$$
