Explicación paso a paso:

$1. a) 2.01\\\\2+0.01\\\\2+\frac{1}{100}\\\\2\frac{1}{100}$

$b)0.4\\\\\frac{0.4\cdot \:10}{10}\\\\\frac{4}{10}\\\\\frac{2}{5}$

$c)3.23\\\\3+0.23\\\\3+\frac{23}{100}\\\\3\frac{23}{100}$

$2. a) \left(\frac{2}{8}+\frac{1}{5}\right)-\left(\frac{1}{8}+\frac{2}{5}\right)\\\\\frac{1}{4}+\frac{1}{5}-\left(\frac{1}{8}+\frac{2}{5}\right)\\\\\frac{1}{4}+\frac{1}{5}-\frac{21}{40}\\\\-\frac{3}{40}$

$b)\left(2-\frac{1}{5}\right)+\left(1+\frac{2}{5}\right)\\\\\frac{9}{5}+\left(1+\frac{2}{5}\right)\\\\\frac{9}{5}+\frac{7}{5}\\\\\frac{16}{5}\\\\3\frac{1}{5}$
