Question

Qual o resultado de:   (3-1/3):(4-3/2)-2/3.5/3

Answer 1

$(3- \frac{1}{3}) : (4-\frac{3}{2}) - \frac{2}{3}. \frac{5}{3} \\ \\ \frac{9-1}{3}: \frac{8-3}{2}- \frac{10}{9}\\ \frac{8}{3} : \frac{5}{2} - \frac{10}{9} \\ \\ \frac{8}{3} . \frac{2}{5} - \frac{10}{9} \\ \\ \frac{16}{15} - \frac{10}{9} = \frac{48-50}{45}= \boxed{-\frac{2}{45}}}$

Answer 2

 (3-1/3):(4-3/2)-2/3.5/3 =
  8/3 : 5/2 - 10/9=
  8/3 * 2/5 - 10/9 =
 16/15 - 10/9 = ----mmc(15,9) = 45
 48/45 - 50/45 = - 2/45
