Answer 1

Respuesta:

-203/225

Explicación paso a paso:

  [(-2/5) - (-2/3) · (-1/4)] : (-5/6) + (-2/9) =

= [(-2/5) - (2/3·4)] : (-5/6) + (-2/9) =

= [(-2/5) - (1/6)] : (-5/6) + (-2/9) =

= [(-12/30) - (5/30)] : (-5/6) + (-2/9) =

= (-17/30) : (-5/6) + (-2/9) =

= (17·6 / 30·5) + (-2/9) =

= (17 / 5·5) + (-2/9) =

= (17/25) + (-2/9) =

= 153/225 - 50/225 =

= 103/225
