9514 1404 393

Answer:

y = 3

Explanation:

Multiply both sides of the equation by 9 to eliminate the denominator.

`\displaystyle(y)/(9)=(4)/(12)\\\\(y)/(9)\cdot9=(1)/(3)\cdot9\qquad\text{multiply by 9, simplify fraction}\\\\y=(9)/(3)\qquad\text{clean up a bit}\\\\\boxed{y=3}\qquad\text{perform the division}`
