Answer 1

Respuesta:

-27/100

Explicación paso a paso:

((1/3 - 0,5) x (2 - 1/5)) : (1 - 1/3)

((1/3 - 5/10) x (2/1 - 1/5)) : (1/1 - 1/3)

(( (10×1-3×5)/3×10 ) x ( (2×5 - 1×1)/1×5 )) : ( (1×3-1×1)/1×3 )

(( (10-15)/30 ) x ( (10 - 1)/5 )) : ( (3-1)/3 )

(( (-5)/30 ) x ( (9)/5 )) : ( (2)/3 )

(( -5/30 ) x ( 9/5 )) : ( 2/3 )

( -1/10 x 9/5 ) : ( 2/3 )

( -1×9/10×5 ) : ( 2/3 )

( -9/50 ) : ( 2/3 )

-9/50  :  2/3

-9×3/50×2

-27/100
