28,(1)=28 intregi 1/9 = 253/9
0,(2)=2/9

3/7 • (253/9 - 745/27) • 9/2 =
3/7 • (759-745)/27 • 9/2 =
3/7 • 14/27 • 9/2 =

3/7 x ( 28,(1) - 745/27 ) : 0,(2) =
28,(1) =28intreg 1/9 =(28x9+1)/9 =253/9
0,(2) =2/9
3/7 x ( 253/9 -745/27) : 2/9 =
3/7 x ( 759/27 - 745/27 ) : 2/9 =
3/7 x 14/27 x 9/2 = simplific 3 si 27 prin 3 , simplific 7 si 14 prin 7= 2/9 x 9/2 =1
