$$\frac{ 1 }{ 4 } + \frac{ 2 }{ 4 } + \frac{ 9 }{ 10 } + \frac{ 5 }{ 10 } =$$
$\frac{43}{20}=2.15$
$$\frac{1+2}{4}+\frac{9}{10}+\frac{5}{10}$$
$$\frac{3}{4}+\frac{9}{10}+\frac{5}{10}$$
$$\frac{15}{20}+\frac{18}{20}+\frac{5}{10}$$
$$\frac{15+18}{20}+\frac{5}{10}$$
$$\frac{33}{20}+\frac{5}{10}$$
$$\frac{33}{20}+\frac{1}{2}$$
$$\frac{33}{20}+\frac{10}{20}$$
$$\frac{33+10}{20}$$
