a)-3/2
b)25/24
c)13/24
d)32/12
e) 45/12

Answer 1

Respuesta:

13/24

Explicación paso a paso:

$(\frac{2}{3} + \frac{1}{2}) - (\frac{1}{4} + \frac{1}{6})(\frac{\frac{1}{2}}{\frac{1}{3}})$

$(\frac{4}{6} + \frac{3}{6}) - (\frac{3}{12} + \frac{2}{12})(\frac{1 \times 3}{2 \times 1})$

$(\frac{7}{6}) - (\frac{5}{12})(\frac{3}{2})$

$(\frac{7\times 4}{6 \times 4}) - \frac{5 \times 3}{12 \times 2}$

$(\frac{28}{24}) - \frac{15}{24}$

$(\frac{13}{24})$
