f=\frac{1}{4}+\frac{1}{2}
Add \frac{1}{2} to both sides.
f=\frac{1}{4}+\frac{2}{4}
Least common multiple of 4 and 2 is 4. Convert \frac{1}{4} and \frac{1}{2} to fractions with denominator 4.
f=\frac{1+2}{4}
Since \frac{1}{4} and \frac{2}{4} have the same denominator, add them by adding their numerators.
f=\frac{3}{4}
Add 1 and 2 to get 3.
