Question

Como faço (2/3:4/5+1/2):(1-3/5•1/6)

Answer 1

$[ \dfrac{2}{3} : \dfrac{4}{5} + \dfrac{1}{2} ]:[1- \dfrac{3}{5} . \dfrac{1}{6} ]$

$[ \dfrac{2}{3} . \dfrac{5}{4} + \dfrac{1}{2} ]:[1- \dfrac{1}{5} . \dfrac{1}{2} ]$

$[ \dfrac{1}{3} . \dfrac{5}{2} + \dfrac{1}{2} ]:[1- \dfrac{1}{10} ]$

$[ \dfrac{5}{6} + \dfrac{1}{2} ]:[\dfrac{10-1}{10} ]$

$[ \dfrac{5+3}{6} ]:[\dfrac{9}{10} ]$

$\dfrac{8}{6} :\dfrac{9}{10}$

$\dfrac{4}{3} :\dfrac{9}{10}$

$\dfrac{4}{3} .\dfrac{10}{9}$

$\dfrac{40}{27}$
