Answer 1

Resposta:

hm

Explicação passo a passo:

a) $\frac{2}{3} + \frac{3}{4} -\frac{4}{5} = \frac{40}{60} + \frac{45}{60} - \frac{48}{60} = \frac{47}{60}$

b) $\frac{8}{24} + \frac{12}{24} + \frac{10}{24} - \frac{2}{24} = \frac{28}{24} = \frac{7}{6}$

c) $\frac{4}{5} . \frac{3}{4} . \frac{5}{2} = \frac{4 . 3 . 5}{5 . 4 . 2} = \frac{60}{40} = \frac{3}{2}$

d) $\frac{8}{12} . \frac{10}{9} = \frac{8 . 10}{12 . 9} = \frac{80}{108} = \frac{20}{27}$

e) $\frac{3}{2} - \frac{1}{3} + \frac{2}{5} = \frac{45}{30} - \frac{10}{30} + \frac{12}{30} = \frac{47}{30}$

acho q esta correto
