Solution Steps

Express \frac{\frac{11\times 10\times 9}{3}}{2} as a single fraction.

$$\frac{11\times 10\times 9}{3\times 2}+\frac{\frac{\frac{\frac{\frac{11\times 10\times 9\times 8\times 7\times 6}{6}}{5}}{4}}{3}}{2}+\frac{\frac{\frac{\frac{\frac{\frac{\frac{\frac{11\times 10\times 9\times 8\times 7\times 6\times 5\times 4\times 3}{9}}{8}}{7}}{6}}{5}}{4}}{3}}{2}$$

Cancel out 2\times 3 in both numerator and denominator.

$$3\times 5\times 11+\frac{\frac{\frac{\frac{\frac{11\times 10\times 9\times 8\times 7\times 6}{6}}{5}}{4}}{3}}{2}+\frac{\frac{\frac{\frac{\frac{\frac{\frac{\frac{11\times 10\times 9\times 8\times 7\times 6\times 5\times 4\times 3}{9}}{8}}{7}}{6}}{5}}{4}}{3}}{2}$$

Multiply 3 and 5 to get 15.
