Example of Simplifying 12+233416\frac{\frac{1}{2}+\frac{2}{3}}{\frac{3}{4}-\frac{1}{6}}

To simplify the complex fraction 12+233416\frac{\frac{1}{2}+\frac{2}{3}}{\frac{3}{4}-\frac{1}{6}}, first evaluate the numerator and denominator independently by treating the main fraction bar as a grouping symbol. In the numerator, the least common denominator (LCD) of 22 and 33 is 66. Rewrite the fractions as 36+46\frac{3}{6} + \frac{4}{6} and add to get 76\frac{7}{6}. In the denominator, the LCD of 44 and 66 is 1212. Rewrite the fractions as 912212\frac{9}{12} - \frac{2}{12} and subtract to obtain 712\frac{7}{12}. Rewrite the resulting complex fraction as a division problem: 76÷712\frac{7}{6} \div \frac{7}{12}. Apply the division rule by multiplying by the reciprocal: 76127\frac{7}{6} \cdot \frac{12}{7}. Divide out the common factors of 77 and 66 from the numerator and denominator to arrive at the fully simplified result of 22.
