Answer 2

Let's solve each expression step by step.

1. $\frac{8}{9} - \frac{5}{6} + \frac{2}{3}$

First, find a common denominator, which in this case is 18.

$\frac{8 \times 2}{9 \times 2} - \frac{5 \times 3}{6 \times 3} + \frac{2 \times 6}{3 \times 6}$

$\frac{16}{18} - \frac{15}{18} + \frac{12}{18}$

Now, subtract and add the fractions:

$\frac{16 - 15 + 12}{18}$

$\frac{13}{18}$

2. $\frac{3}{8} - \frac{1}{9} + \frac{25}{36}$

Again, find a common denominator, which in this case is 72.

$\frac{3 \times 9}{8 \times 9} - \frac{8 \times 8}{9 \times 8} + \frac{25 \times 2}{36 \times 2}$

$\frac{27}{72} - \frac{64}{72} + \frac{50}{72}$

Now, subtract and add the fractions:

$\frac{27 - 64 + 50}{72}$

$\frac{13}{72}$
