Answer 2

Answer:

$3 \frac{11}{18}$

Answer A is correct.

Step-by-step explanation:

$12 \frac{4}{9} - 8 \frac{5}{6} \\ \frac{112}{9} - \frac{53}{6} \\ ( \frac{112}{9} \frac{ \times6 }{ \times6 } ) - ( \frac{53}{6} \frac{ \times 9}{ \times 9} ) \\ \frac{672}{54} - \frac{477}{54} \\ = \frac{195}{54} \\ = \frac{65}{18} \\ = 3 \frac{11}{18}$
