2 + $\frac{3}{4}$ ×$\frac{8}{5}$
=2+$\frac{6}{5}$
=2+1,2
=3,2=$\frac{16}{5}$
$\frac{9}{8}$ - $\frac{6}{5}$ : $\frac{8}{5}$
=$\frac{9}{8}$ - $\frac{6}{5}$ . $\frac{5}{8}$
=$\frac{9}{8}$ -$\frac{3}{4}$
=$\frac{9}{8}$ -$\frac{6}{8}$
=$\frac{3}{8}$
6 : $\frac{9}{7}$ .$\frac{3}{10}$
=6 . $\frac{7}{9}$ .$\frac{3}{10}$
=$\frac{14}{3}$ .$\frac{3}{10}$
=$\frac{14}{10}$ =1,4=$\frac{7}{5}$
