Answer 1

1,5 = 15 / 10 = 3 / 2

1,(3) = ( 13 - 1) / 9 = 12 / 9 = 4 / 3

[ ( 3 / 2 × 3 + 3 : 1 / 5 ) × 4 / 3 + 4 ] : 6 =

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

= [ ( 9 / 2 + 30 / 2 ) × 4 / 3 + 4 ] : 6 =

= ( 39 / 2 × 4 / 3 + 4 ) : 6 =

= ( 39 / 3 × 4 / 2 + 4 ) : 6 =

= ( 13 x 2 + 4 ) : 6 =

= ( 26 + 4 ) : 6 =

= 30 : 6 =

= 5
