Answer:
y = 3
Explanation:
You are correct that ...
1/4 = y/12 = 3/12
This means y = 3, the numerator of the fraction with 12 as the denominator.
__
In the original equation, you can get there by multiplying both sides of the equation by 12 (the denominator under y).
12(1/4) = 12(y/12)
12/4 = (12/12)y . . . . simplify a bit
3 = y
