$$2 \frac { 1 } { 10 } \times 1 \frac { 3 } { 8 } \times 3 \frac { 1 } { 11 }$$
$\frac{357}{40}=8.925$
$$\frac{20+1}{10}\times \frac{1\times 8+3}{8}\times \frac{3\times 11+1}{11}$$
$$\frac{21}{10}\times \frac{1\times 8+3}{8}\times \frac{3\times 11+1}{11}$$
$$\frac{21}{10}\times \frac{8+3}{8}\times \frac{3\times 11+1}{11}$$
$$\frac{21}{10}\times \frac{11}{8}\times \frac{3\times 11+1}{11}$$
$$\frac{21\times 11}{10\times 8}\times \frac{3\times 11+1}{11}$$
$$\frac{231}{80}\times \frac{3\times 11+1}{11}$$
$$\frac{231}{80}\times \frac{33+1}{11}$$
$$\frac{231}{80}\times \frac{34}{11}$$
$$\frac{231\times 34}{80\times 11}$$
$$\frac{7854}{880}$$
