Explicație pas cu pas:

1,3 / 13 X = 2,(3) / 0,1(6)

13 X × 2,(3) = 1,3 × 0,1(6)

13 X ×  ( 23 - 2 ) / 9 = 13 / 10  × ( 16 - 1 ) / 90

13 X × ( 21 / 9 ) = ( 13 / 10 ) × ( 15/ 90 )

13 X × ( 7 / 3 ) = 13 / 60

13 X = ( 13 / 60 ) : ( 7 / 3 )

13 X = ( 13 / 60 ) × ( 3 / 7 )

13 X = 13 / 140

X = ( 13 / 140 ) : 13

X = ( 13 / 140 ) × ( 1 / 13 )

X = 1 / 140
