If $$\frac{\left[\left(4.625 - 1\frac{18}{26}\right) \div \frac{7}{8} + (2.5 - 1.25) \div 6.75\right] \div 1\frac{53}{68}}{\left(\frac{1}{2} - 0.375\right) \div 0.125 + \left(\frac{5}{6} - \frac{7}{12}\right) \div (0.358 - 1.4796 \div 13.7)} = \frac{17}{27}$$ then $$x = $$ ______.

TO BE FILLED - the printed expression contains no $$x$$ and its computed value is not $$\frac{17}{27}$$, so the statement must be re-read from the paper before the answer is filled in. The denominator does simplify neatly, since $$(0.5 - 0.375) \div 0.125 = 1$$ and $$\frac{1}{4} \div (0.358 - 0.108) = 1$$, giving 2.
