Answer 1

a)8/3 × 81/64 = 27/8

b)3/4 × 4 - 4/9 = 23/9

Answer 2

$a)(3 - \frac{1}{3} ) \times ( \frac{9}{8} ){}^{2} \\ \frac{8}{3} \times \frac{81}{64} \\ = \frac{27}{8}$
$b) \frac{3}{4} \div ( \frac{3}{4} - \frac{1}{2}) - \frac{4}{9} \\ = \frac{3}{4} \div \frac{1}{4} - \frac{4}{9} \\ = \frac{3}{4} \times 4 - \frac{4}{9} \\ = 3 - \frac{4}{9} \\ = \frac{23}{9}$
