Answer 1

    $\frac{9}{8}\div \frac{27}{4}+\left(\frac{3}{4}\cdot \frac{8}{5}-\frac{3}{10}\right)$

• Calculemos todo del parentesis.-

    $\left(\frac{3}{4}\cdot \frac{8}{5}-\frac{3}{10}\right)\\\\\frac{6}{5}-\frac{3}{10}\\\\\frac{12}{10}-\frac{3}{10}\\\\\frac{12-3}{10}\\\\\frac{9}{10}$

• Seguimos con el ejercicio.-

    $\frac{9}{8}\div \frac{27}{4}+\frac{9}{10}$

• Calculemos.- $\frac{9}{8}\div \frac{27}{4}$

    $\frac{9}{8}\div \frac{27}{4}\\\\\frac{9\cdot \:4}{8\cdot \:27}\\\\\frac{36}{8\cdot \:27}\\\\\frac{36}{216}\\\\\frac{1}{6}$

• Seguimos con el ejercicio.-

   $\frac{1}{6}+\frac{9}{10}\\\\\frac{16}{15}\\\\1\frac{1}{15}$
