Question

operaciones combinadas usando paréntesis

Answer 1

$1. ( \frac{3}{4}+ \frac{18}{2} )+ ( \frac{7}{3}- \frac{3}{2} ) = ( \frac{12 + 36}{4} )+ (\frac{14-9}{6} )= \frac{48}{4} + \frac{5}{6}= \frac{144+10}{12} = \frac{154}{12} \\ \\ 2.( \frac{4}{9}+ \frac{5}{2} )+ ( \frac{3}{4}- \frac{1}{6} )= ( \frac{8+45}{18} )+( \frac{9-2}{12} )= \frac{53}{18} + \frac{7}{2} = \frac{53+63}{18}= \frac{116}{18}$
