$\frac{8}{20}$ $8/20$ or $\frac{2}{5}$ $2/5$

First, get all the fractions over a common denominator, in this case $20$ $20$

$((\frac{10}{10} \cdot \frac{1}{2})) + \frac{3}{20}) - \frac{2}{20} \Rightarrow$ $((10/10 * 1/2)) + 3/20) - 2/20 =>$

$(\frac{10}{20} + \frac{3}{20}) - \frac{2}{20}$ $(10/20 + 3/20) - 2/20$

Next, add the terms within parenthesis:

$\frac{13 + 3}{20} - \frac{2}{20} \Rightarrow$ $(13 + 3)/20 - 2/20 =>$

$\frac{16}{20} - \frac{2}{20} \Rightarrow$ $16/20 - 2/20 =>$

$\frac{16 - 2}{20} \Rightarrow$ $(16 - 2)/20 =>$

$\frac{8}{20} \Rightarrow$ $8/20 =>$

$(\frac{4}{4}) (\frac{2}{5}) \Rightarrow$ $(4/4)(2/5) =>$

$\frac{2}{5}$ $2/5$
