Answer 1

Explicación paso a paso:

$(( 3\frac{1}{4} + 3 \frac{3}{8} ) - 2.25) + 1 \frac{1}{8} \\ \\ = (( 3\frac{1 \times 2}{4 \times 2} + 3 \frac{3}{8} ) - \frac{225}{100} ) + 1 \frac{1}{8} \\ \\ = ((3 \frac{2}{8} + 3 \frac{3}{8} ) - 2\frac{1}{4} ) + 1 \frac{1}{8} \\ \\ =( ( \frac{26}{8} + \frac{27}{8}) - 2\frac{1 \times 2}{4 \times 2} ) + 1 \frac{1}{8} \\ \\ = ( \frac{53}{8} - 2 \frac{2}{8}) + \frac{9}{8} \\ \\ = \frac{53}{8} - \frac{18}{8} + \frac{9}{8} \\ \\ = \frac{44}{8} = \frac{11}{2}$

$(( \frac{9}{7} - 0.75) + \frac{13}{28} ) - \frac{11}{14} + \frac{8}{28} \\ \\ = (( \frac{9}{7} - \frac{3}{4} )+ \frac{13}{28} ) - \frac{11}{14} + \frac{8}{28} \\ \\ =( \frac{36 - 21}{28} + \frac{13}{28} )- \frac{11 \times 2}{14 \times 2} + \frac{8}{28} \\ \\ = \frac{15}{28} + \frac{13}{28} - \frac{22}{28} + \frac{8}{28} \\ \\ = \frac{15 + 13 - 22 + 8}{28} \\ \\ = - \frac{14}{28} \\ \\= \frac{1}{2}$
