$$\frac{ 3 }{ 4 } + \frac{ 5 }{ 9 } \times \frac{ \frac{ 3 }{ 2 } }{ \frac{ 2 }{ 3 } } + \frac{ 1 }{ 5 }$$
$\frac{11}{5}=2.2$
$$\frac{3}{4}+\frac{5}{9}\times \frac{3}{2}\times \frac{3}{2}+\frac{1}{5}$$
$$\frac{3}{4}+\frac{5}{9}\times \frac{3\times 3}{2\times 2}+\frac{1}{5}$$
$$\frac{3}{4}+\frac{5}{9}\times \frac{9}{4}+\frac{1}{5}$$
$$\frac{3}{4}+\frac{5\times 9}{9\times 4}+\frac{1}{5}$$
$$\frac{3}{4}+\frac{5}{4}+\frac{1}{5}$$
$$\frac{3+5}{4}+\frac{1}{5}$$
$$\frac{8}{4}+\frac{1}{5}$$
$$2+\frac{1}{5}$$
$$\frac{10}{5}+\frac{1}{5}$$
$$\frac{10+1}{5}$$
$$\frac{11}{5}$$
