Answer
$\frac{7}{18}$
Work Step by Step
$\frac{11}{18} - \frac{2}{9}$
the least common denominator for the denominators 18 and 9 is 18.
To obtain denominators of 18, multiply the numerator and denominator of the second fraction by 2
$\frac{11}{18} - \frac{2}{9}$ = $\frac{11}{18} - \frac{2*2}{9*2}$
$\frac{11}{18} - \frac{4}{18}$
Calculate difference of the numerators and put this difference over the least common denominator.
$\frac{11-4}{18}$ = $\frac{7}{18}$
