Answer 1

Respuesta:

a.

$\frac{2}{3} + \frac{3}{4} \\ \frac{(2 \times 4) + (3 \times 3)}{3 \times 4 } \\ \frac{8 + 9}{12} \\ \frac{17}{12}$

b.

$\frac{8}{5} - \frac{1}{2} \\ \frac{(8 \times 2) - (5 \times 1)}{5 \times 2} \\ \frac{16 - 5}{10} \\ \frac{11}{10}$

c.

$\frac{1 }{6} + \frac{4}{5} - \frac{7}{10} \\ \frac{(1 \times 5) + (6 \times 4)}{6 \times 5} - \frac{7}{10} \\ \frac{5 + 24}{30} - \frac{7}{10} \\ \frac{29}{30} - \frac{7}{10} \\ \frac{(29 \times 10) - (30 \times 7)}{30 \times 10} \\ \frac{290 - 210}{300} \\ \frac{80}{300} = \frac{4}{15}$

d.

$\frac{11}{6} - \frac{5}{4} + \frac{2}{3} \\ \frac{(11 \times 4) - (6 \times 5)}{6 \times 4} + \frac{2}{3} \\ \frac{44 - 30}{24} + \frac{2}{3} \\ \frac{14}{24} + \frac{2}{3} \\ \frac{7}{12} + \frac{2}{3} \\ \frac{(7 \times 3) + (12 \times 2)}{12 \times 3} \\ \frac{21 + 24}{36} \\ \frac{45}{36} = \frac{5}{4}$
