Answer 1

Respuesta:

$\frac{7}{4} + \frac{5}{12} - \frac{3}{8} - \frac{2}{3} = \frac{42 + 10 - 9 - 16}{24} = \frac{27}{24} = \frac{9}{8}$

$( \frac{1}{6} + \frac{3}{4}) \div ( \frac{5}{3} + \frac{3}{2} ) \\ \frac{22}{24} \div \frac{19}{6} = \frac{22}{24} \times \frac{6}{19} = \frac{132}{456} = \frac{11}{38}$
