Answer 2

[0,(6) + 5,(6) ] x ( 0,6 + 0,6 : 2 ) = ?

0,(6) = 6 / 9 = 2 / 3

5,(6) = ( 56 - 5 ) / 9 = 51 / 9 = 17 / 3

0,6 = 6 / 10 = 3 / 5

( 2 / 3 + 17 / 3 ) × ( 3 / 5 + 3 / 5 × 1 / 2 ) =

= 19 / 3 × ( 3 / 5 + 3 / 10 ) =

= 19 / 3 × ( 6 + 3) / 10 =

= ( 19 × 9 ) /( 3 × 10 ) =

= 171 / 30 =

= 57 / 10 =

= 5,7
