Answer 1

a)


1, (3) = 13-1/9= 12/9=4/3
2, (12)= 212-2/99= 210/99=70/33
5 ,( 5) = 55-5/9= 50/9
7, (4)=74-7 / 9 =67/9
0, ( 13 )=13/99
2, (43)=243-2/99=241/99
 72,(15 )=7215-72/99= 7143/ 99= 2381/33

b)0, (6)=6/9=2/3
3, (4)=34-3/9= 31/9
 8,(15)=815-8/9 =807/9 =269/3
0, (23)=23/99
0, (40)=40/99
5,(73)= 573-5/99= 568/99
81,(05)= 8105-81/99= 8024/99
0, (23)=23/99
