Answer 1

Răspuns:

1,6(1)=(161-16)/90=(145/90)⁽⁵=29/18

3,3(8)=(338-33)/90=(305/90)⁽⁵=61/18

1,(2)=(12-1)/9=11/9

29/18-61/18-²⁾11/9=29/18-61/18-22/18=-54/18=-3 numarator

6:(6×3+2)/3-(6×5+3)/5·(1×22+3)/22-2/5=

6:20/3-33/5×25/22-2/5=

6×3/20-15/2-2/5=

18/20-¹⁰⁾15/2-⁴⁾2/5=

36/20-150/20-8/20= -140/20= -7 numitor

-3/7 rezultatul

am calculat defalcat ca sa intelegi
