(1 7/9 - 1 1/3)/(5/9 - 0,6 : 1 4/5) = ( 1 21/27 - 1 9/27)/(5/9 - 6/10 : 9/5) =

= 1 12/27 : ( 5/9 - 6/10 * 5/9) = 1 12/27 : ( 5/9 - 2/2 * 1/3) =

= 1 12/27 : ( 5/9 - 1 * 1/3) = 1 12/27 : ( 5/9 - 1/3) = 1 12/27 : (5/9 - 3/9) =

= 1 12/27 : 2/9 = 39/27 : 2/9 = 39/27 * 9/2 = 39/3 * 1/2 = 13 * 1/2 =

= 13/2 = 6 1/2
