$$\frac { 3 } { 2 } \quad 1 \frac { 2 } { 5 } + 2 \frac { 6 } { 10 } + \frac { 1 } { 2 }$$
$\frac{26}{5}=5.2$
$$\frac{3}{2}\times \frac{5+2}{5}+\frac{2\times 10+6}{10}+\frac{1}{2}$$
$$\frac{3}{2}\times \frac{7}{5}+\frac{2\times 10+6}{10}+\frac{1}{2}$$
$$\frac{3\times 7}{2\times 5}+\frac{2\times 10+6}{10}+\frac{1}{2}$$
$$\frac{21}{10}+\frac{2\times 10+6}{10}+\frac{1}{2}$$
$$\frac{21}{10}+\frac{20+6}{10}+\frac{1}{2}$$
$$\frac{21}{10}+\frac{26}{10}+\frac{1}{2}$$
$$\frac{21+26}{10}+\frac{1}{2}$$
$$\frac{47}{10}+\frac{1}{2}$$
$$\frac{47}{10}+\frac{5}{10}$$
$$\frac{47+5}{10}$$
$$\frac{52}{10}$$
$$\frac{26}{5}$$
