\frac{\frac{3\left(2x-y\right)}{6x\left(2x-y\right)}}{\frac{1}{x}-\frac{3}{4x}}
Factor the expressions that are not already factored in \frac{6x-3y}{12x^{2}-6xy}.
\frac{\frac{1}{2x}}{\frac{1}{x}-\frac{3}{4x}}
Cancel out 3\left(2x-y\right) in both numerator and denominator.
\frac{\frac{1}{2x}}{\frac{4}{4x}-\frac{3}{4x}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and 4x is 4x. Multiply \frac{1}{x} times \frac{4}{4}.
\frac{\frac{1}{2x}}{\frac{1}{4x}}
Since \frac{4}{4x} and \frac{3}{4x} have the same denominator, subtract them by subtracting their numerators. Subtract 3 from 4 to get 1.
\frac{4x}{2x}
Divide \frac{1}{2x} by \frac{1}{4x} by multiplying \frac{1}{2x} by the reciprocal of \frac{1}{4x}.
