c) 0,125 si 0,1(8)
d) 34 supra 9 si 26 supra 7 .
Va rog rapid

Answer 1

a) 2,5=2,500...
2,5(3)=2,533...
2,5<2,52<2,5(3)

b) 7:3= 2,(3)
2,(3)=2,333...
2,4= 2,400...
2,(3)<2,35<2,4

c)0,125=0,12500...
0,1(8)=0,18888...
0,125<0,15<0,1(8)

d)34:9=3,(7)
26:7=3,71(42)
3,(7)=3,7777777...
3,71(42)=3,71424242...
3,(7)>3,72>3,71(42)
