Dear Student, Since your question is not clear, I am assuming it is 11 + 1611 + 16 = 16 + 16 = 176 = 67

1+1/1+1/6

Dear Student,

S i n c e y o u r q u e s t i o n i s n o t c l e a r, I a m a s s u m i n g i t i s \frac{1}{1 + \frac{1}{6}} \frac{1}{1 + \frac{1}{6}} = \frac{1}{\frac{6 + 1}{6}} = \frac{1}{\frac{7}{6}} = \frac{6}{7}
