$\frac{1}{6}$ $1/6$

find common denominators to make the subtraction easier

$\frac{6}{7} . (\frac{11}{18} - \frac{5}{12})$ $6/7 . (11/18 - 5/12)$

$\frac{6}{7} . (\frac{22}{36} - \frac{15}{36})$ $6/7 . (22/36 - 15/36)$

$\frac{6}{7} . \frac{7}{36}$ $6/7 . 7/36$

the 7's cancel each other out

$\frac{6}{36}$ $6/36$

$\frac{1}{6}$ $1/6$
