Question

resolva a operação a seguir.

Answer 1

$- 1.999... + \frac{ \frac{1}{5} + \frac{1}{3} }{ \frac{3}{5} - \frac{1}{5} } \\ \\ - 1.999... + \frac{ \frac{8}{15} }{ \frac{2}{5} } \\ \\ - 1.999 ... + \frac{8 \times 5}{15 \times 2} \\ \\ - 1.999... + \frac{40}{30} \\ \\ - 1.999... + \frac{4}{3} \\ \\ - 0.665667$

Answer 2

Oie, tudo bom?!

$≈ - 1,999... + \frac{ \frac{1}{5} + \frac{1}{3} }{ \frac{3}{5} - \frac{1}{5} } \\ ≈ - 1,999... + \frac{ \frac{3 + 5}{15} }{ \frac{3 - 1}{5} } \\ ≈ - 1,999... + \frac{ \frac{8}{15} }{ \frac{2}{5} } \\ ≈ - 1,999... + \frac{8}{15} \div \frac{2}{5} \\ ≈ - 1,999... + \frac{8}{15} \: . \: \frac{5}{2} \\ ≈ - 1,999... + \frac{8 \: . \: 5}{15 \: . \: 2} \\ ≈ - 1,199... + \frac{4 \: . \: 2}{15} \\ ≈ - 1,999... + \frac{4}{3} \\ ≈ - 1,999... + 1,33333... \\ \boxed{ ≈ - 0,665667...}$
