d=\frac{4}{12}-\frac{3}{12}
Least common multiple of 3 and 4 is 12. Convert \frac{1}{3} and \frac{1}{4} to fractions with denominator 12.
d=\frac{4-3}{12}
Since \frac{4}{12} and \frac{3}{12} have the same denominator, subtract them by subtracting their numerators.
d=\frac{1}{12}
Subtract 3 from 4 to get 1.
