Answer 1

Hola!

Explicación paso a paso:

b)

$\frac{5}{12} + \frac{3}{4} - ( \frac{1}{6} + \frac{1}{2} ) \\ = \frac{5}{12} + \frac{3 \times 3}{4 \times 3} - ( \frac{1}{6} + \frac{1 \times 3}{2 \times 3} ) \\ = \frac{5}{12} + \frac{9}{12} - ( \frac{1}{6} + \frac{3}{6} ) \\ = \frac{5 + 9}{12} - ( \frac{1 + 3}{6} ) \\ = \frac{14}{12} - ( \frac{4}{6} ) \\ = \frac{7}{6} - \frac{4}{6} \\ = \frac{7 - 4}{6} \\ = \frac{3}{6 } \\ = \frac{1}{2}$

c)

$6 + ( \frac{4}{5} - \frac{2}{3} ) \\ 6 + ( \frac{4(3) - 2(5)}{5(3)} ) \\ 6 + ( \frac{12 - 10}{15} ) \\ 6 + ( \frac{2}{15} ) \\ \frac{6(15) + 2}{15} \\ \frac{90 + 2}{15} \\ \\ \frac{92}{15}$
