Question

sobre Conjunto de Números Racionais Q ​

Answer 1

Resposta:

a)

$\frac{15+16}{24} = \frac{31}{24}$

b)

$\frac{2-9}{12} =\frac{-7}{12}$

c)

$\frac{1}{4} +\frac{7}{6} = \frac{3+14}{12} = \frac{17}{12}$

d)

$\frac{7}{5} *\frac{7}{9} = \frac{49}{45}$

e)

$\frac{55}{24}$

f)

$\frac{1}{2} +\frac{15}{8} = \frac{4+15}{8} = \frac{19}{8}$

g)

$\frac{5}{4} -\frac{1}{2}* \frac{3}{2} +\frac{5}{6} = \frac{5}{4} -\frac{3}{4} +\frac{5}{6} = \frac{15-9+10}{12} = \frac{16}{12} = \frac{8}{6} = \frac{4}{3}$
