Me ayudan? Es una fracción

Answer 1

$6)( \frac{8}{12} + \frac{1}{12} ) \times \frac{12}{3 } = \frac{9}{12} \times \frac{12}{3} = 3$

$7)( \frac{45}{30} + \frac{1}{6} + \frac{1}{5} ) - \frac{2}{30} = ( \frac{45}{30} + \frac{5}{30} + \frac{6}{30} ) - \frac{2}{30} = \frac{45 + 5 + 6}{ 30} - \frac{2}{30} = \frac{56}{30} - \frac{2}{30} = \frac{54}{30 } = \frac{9}{5}$

$8)( \frac{28}{7} + \frac{3}{4} ) \times \frac{1}{2} = ( \frac{112}{28} + \frac{21}{28} ) \times \frac{1}{2} = \frac{133}{28} \times \frac{1}{2} = \frac{133}{56} = \frac{19}{8}$

$9)( \frac{12}{5} + \frac{1}{3} ) - ( \frac{1}{2} + \frac{1}{2} ) = ( \frac{36}{15} + \frac{5}{15} ) - \frac{2}{2} = ( \frac{36}{15} + \frac{5}{15} ) - 1 = \frac{41}{15} - 1 = \frac{41}{15} - \frac{15}{15} = \frac{26}{15}$
