Question

(3/5•1,(6)-5/6):[-0,1(6)]= pls varig repede

Answer 1

Răspuns:

Explicație pas cu pas:

(3/5•1,(6)-5/6):[-0,1(6)]= (3/5 · 15/9 - 5/6): (-15/90) =

= [(3·15)/(5·9) - 5/6]:(-1/6) = (⁶⁾1-5/6):(-1/6) = 1/6 :(-1/6) = -1

Answer 2

( 3/5 × 1,(6) - 5/6 ) : :[ - 0,1(6) ]

1,(6) = 16 - 1/9 = 15/9

0,1(6) = 16 - 1/90 = 15/90 = 1/6

( 3/5 × 15/9 - 5/6 ) : ( - 1/6 ) =

( 3/3 - 5/6 ) : ( - 1/6 ) =

( 1 - 5/6 ) : ( - 1/6 ) = 1/6 : ( - 1/6 ) = - 1
