$$\frac{ 1 }{ 2 } \times + \frac{ 11 }{ 2 } - \frac{ 2 }{ 5 } \times - \frac{ 3 }{ 5 } =5$$
$\text{false}$
$$\frac{1\times 11}{2\times 2}-\frac{2}{5}\left(-\frac{3}{5}\right)=5$$
$$\frac{11}{4}-\frac{2}{5}\left(-\frac{3}{5}\right)=5$$
$$\frac{11}{4}-\frac{2\left(-3\right)}{5\times 5}=5$$
$$\frac{11}{4}-\frac{-6}{25}=5$$
$$\frac{11}{4}-\left(-\frac{6}{25}\right)=5$$
$$\frac{11}{4}+\frac{6}{25}=5$$
$$\frac{275}{100}+\frac{24}{100}=5$$
$$\frac{275+24}{100}=5$$
$$\frac{299}{100}=5$$
$$\frac{299}{100}=\frac{500}{100}$$
$$\text{false}$$
