Va rog ajutor am nevoie rapid

Answer 1

0,3=3/10
4,53=453/100
0,(3)=3/9=1/3
0 ,5(8)=(58-5)/90=53/90
3,(07823)=(307823-3)/99999=307820/99999
1,4(52)=(1452-14)/990=1438/990=719/495

2/3=0,(6)
7/5=1,4
11/30=0,3(6)

a) 0,36×1/6+0,18:0,03=
 =0,06+6=6,06


b) (5,4-1,7)×5,2-(10,22-83/10)×9,5=
= 3,7×5,2-(10,22-8,3)×9,5=
= 19,24-1,92×9,5=
= 19,24-18,24=1
