Option D:

The solution to the equation is y = 27.

Solution:

Given equation:

$$\frac{1}{3} y=9$

To solve this equation:

$$\frac{1}{3} y=9$

Multiply by 3 on both sides of the equation.

$$3 \times \frac{1}{3} y=9 \times 3$

3 in the numerator and denominator get canceled.

y = 9 × 3

y = 27

The solution to the equation is y = 27.

Option D is the correct answer.
