Answer 1

Răspuns:

Explicație pas cu pas:

0.8(3) = (83-8)/90=75/90=5/6

0.0(27)=27/990=3/110

0.91(6)=(916-91)/900=825/900=11/12

2.(123) = (2123-2)/999=2121/999=707/333

0.41(6) = (416-41)/900=375/900=5/12

1.23(7)=(1237-123)/900=1114/900=557/450

19.(45)=(1945-19)/99=1926/99=214/11

2.4(8) =(248-24)/90=224/90=112/45
