(6/35-7/7)-(-1,8+(4,3))-5,5

( 6/35-¹ 7/7) -³ ( - 1,8 +² 4,3) -⁴ 5,5 =

1) 6/35 - 7/7 = 6/35 - 35/35 = - ( 35/35 - 6/35) =

- 29/35

2) - 1,8 + 4,3 = 4,3 - 1,8 = 2,5

3) - 29/35 - 2,5 = - 29/35 - 25/10 = - 290/350 - 875/350 = - ( 290/350 + 875/350 ) = - 1165/350 = - 233/70

4) - 233/70 - 5,5 = - 233/70 - 55/10 = - 233/70 - 385/70 = - ( 233/70 + 385/70 ) = - 618/70 = - 309/35 = - 8 целых 29/35
