Explicação passo a passo:

$\frac{16}{9} - 1\\\\\frac{16}{9} - \frac{9}{9}\\\\\frac{7}{9}$

--

$\frac{2}{3} + \frac{1}{9} \\\\\frac{6}{9} + \frac{1}{9} \\\\\frac{7}{9}$

--

$\frac{3}{2} + \frac{1}{4} - 8\\\\\\\frac{6}{4} + \frac{1}{4} - \frac{32}{4} \\\\\frac{39}{4}$

$1 + \frac{3}{5} + \frac{1}{4} \\\\\frac{20}{20} +\frac{12}{20} +\frac{4}{20} \\\\\frac{36}{20}$
