Answer 1

Step-by-step explanation:

sum of 1/3 and 6/3=1+6/3

=7/3

sum of 7/9 and 5/6=7+5/18

=12/18

12/18-7/3=5/18

Answer 2

$\frac{1}{3} + \frac{6}{3} -( \frac{7}{9} - \frac{5}{6} ) \\ \\ = \frac{1 + 6}{3} - ( \frac{2 \times 7 - 3 \times 5}{18} ) \\ \\ = \frac{7}{3} - ( \frac{14 - 15}{18} ) \\ \\ = \frac{7}{3} - ( - \frac{1}{18} ) \\ \\ = \frac{7}{3} + \frac{1}{18} \\ \\ = \frac{42 + 1}{18} \\ \\ = \frac{43}{18}$
