Answer 1

A) 0,7(5)=(75-7)/90=68/90=34/45
0,1(2)=(12-1)/90=11/90
4,7(3)=4 intregi si (73-7)/90=4 intregi si 66/90=(4x90+66)/90=426/90=71/15
5,9(6)=5 intregi si (96-9)/90=5 intregi si 87/90=(5x90+87)/90=537/90=179/30
7,1(7)=7 intregi si (17-1)/90=7 intregi si 16/90=(7x90+16)/90=646/90=323/45

B) 0,21(5)=(215-21)/900=194/900=97/450
0,23(4)=(234-23)/900=211/900
1,51(3)=1 intreg si (513-51)/900=1 intreg si 462/900=(1x900+462)/900=1362/900=227/150
2,72(4)=2 intregi si (724-72)/900=2 intregi si 652/900=(2x900+652)/900=2452/900=613/225
9,15(3)=9 intregi si (153-15)/900=9 intregi si 138/900=(9x900+138)/900=8238/900=1373/150
