Answer 1

$( \frac{38}{9} - 1.5) \div ( \frac{31}{2} + 0.8) + 2(4) = ( \frac{38}{9} - \frac{3}{2} ) \div ( \frac{31}{2} + \frac{4}{5} ) + 8 = \frac{49}{18} \div \frac{163}{10} + 8 = \frac{49}{18} \times \frac{10}{163} + 8 = \frac{49}{9} \times \frac{5}{163} + 8 = \frac{245}{1467} + 8 = \frac{11981}{1467} .$
