\frac{x}{\frac{4}{30}+\frac{5}{30}}=\frac{\frac{1}{9}+\frac{1}{5}}{\frac{1}{3}-\frac{1}{6}}
Least common multiple of 15 and 6 is 30. Convert \frac{2}{15} and \frac{1}{6} to fractions with denominator 30.
\frac{x}{\frac{4+5}{30}}=\frac{\frac{1}{9}+\frac{1}{5}}{\frac{1}{3}-\frac{1}{6}}
Since \frac{4}{30} and \frac{5}{30} have the same denominator, add them by adding their numerators.
\frac{x}{\frac{9}{30}}=\frac{\frac{1}{9}+\frac{1}{5}}{\frac{1}{3}-\frac{1}{6}}
Add 4 and 5 to get 9.
\frac{x}{\frac{3}{10}}=\frac{\frac{1}{9}+\frac{1}{5}}{\frac{1}{3}-\frac{1}{6}}
Reduce the fraction \frac{9}{30} to lowest terms by extracting and canceling out 3.
\frac{x}{\frac{3}{10}}=\frac{\frac{5}{45}+\frac{9}{45}}{\frac{1}{3}-\frac{1}{6}}
Least common multiple of 9 and 5 is 45. Convert \frac{1}{9} and \frac{1}{5} to fractions with denominator 45.
\frac{x}{\frac{3}{10}}=\frac{\frac{5+9}{45}}{\frac{1}{3}-\frac{1}{6}}
Since \frac{5}{45} and \frac{9}{45} have the same denominator, add them by adding their numerators.
\frac{x}{\frac{3}{10}}=\frac{\frac{14}{45}}{\frac{1}{3}-\frac{1}{6}}
Add 5 and 9 to get 14.
\frac{x}{\frac{3}{10}}=\frac{\frac{14}{45}}{\frac{2}{6}-\frac{1}{6}}
Least common multiple of 3 and 6 is 6. Convert \frac{1}{3} and \frac{1}{6} to fractions with denominator 6.
\frac{x}{\frac{3}{10}}=\frac{\frac{14}{45}}{\frac{2-1}{6}}
Since \frac{2}{6} and \frac{1}{6} have the same denominator, subtract them by subtracting their numerators.
\frac{x}{\frac{3}{10}}=\frac{\frac{14}{45}}{\frac{1}{6}}
Subtract 1 from 2 to get 1.
\frac{x}{\frac{3}{10}}=\frac{14}{45}\times 6
Divide \frac{14}{45} by \frac{1}{6} by multiplying \frac{14}{45} by the reciprocal of \frac{1}{6}.
\frac{x}{\frac{3}{10}}=\frac{14\times 6}{45}
Express \frac{14}{45}\times 6 as a single fraction.
\frac{x}{\frac{3}{10}}=\frac{84}{45}
Multiply 14 and 6 to get 84.
\frac{x}{\frac{3}{10}}=\frac{28}{15}
Reduce the fraction \frac{84}{45} to lowest terms by extracting and canceling out 3.
x=\frac{28}{15}\times \frac{3}{10}
Multiply both sides by \frac{3}{10}.
x=\frac{28\times 3}{15\times 10}
Multiply \frac{28}{15} times \frac{3}{10} by multiplying numerator times numerator and denominator times denominator.
