Answer 1

Explicación paso a paso:

$\frac{1}{2} ( \frac{7}{4} - \frac{3}{4}) = \\ (\frac{1}{2} \times \frac{7}{4} ) - ( \frac{1}{2} \times \frac{3}{4} ) = \\ \frac{7}{8} - \frac{3}{8} = \\ \frac{7 - 3}{8} = \frac{4}{8} = \frac{1}{2}$

$- 4.6( - 7.2 + 3 \times \frac{1}{2} ) = \\ ( - 4.6 \times - 7.2) + ( - 4.6 \times 3 \times \frac{1}{2} ) = \\ 33.12 + \frac{ - 69}{10} = \\ 26.22$

$- 3(4 + 5 - 6) = \\ ( - 3 \times 4) + ( - 3 \times 5) - ( - 3 \times 6) = \\ - 12 + ( - 15) + 18 = \\ - 27 + 18 = - 9$
