a. By definition, the Quotient is the result of a Division.
A Division can be written as a fraction:
![(a)/(b)](https://img.qammunity.org/2023/formulas/mathematics/college/g8sir66zlcc8xwmqjmo76p2u42j0ie751n.png)
Where "a" is the numerator and "b" is the denominator.
You also need to remember that word "is" indicates that you must use:

Knowing the explained above, you can set up the following equation using the information given in the exercise:
![(y)/(3)=-9](https://img.qammunity.org/2023/formulas/mathematics/college/vus9m9t5kq6yotvx3dq6khh2jav2j0kgkl.png)
b. You need to solve for "y" in order to find its value. You can apply the Multiplication property of equality by multiplying both sides of the equation by 3. Then:
![\begin{gathered} ((y)/(3))(3)=(-9)(3) \\ \\ y=-27 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/sgka8auvaa6f9mr7mb4265x7ws7t9108pl.png)
The answers are:
a.
![(y)/(3)=-9](https://img.qammunity.org/2023/formulas/mathematics/college/vus9m9t5kq6yotvx3dq6khh2jav2j0kgkl.png)
b.
