1,(3), 1,5(6), 17,3(24), 0,2(3), 3,0(24), 4,005, 72,(15), 2,75

Answer 1

1,(3) = ( 13 - 1 ) / 9 = 12 / 9 = 4 / 3

1,5 ( 6 ) = ( 156 - 15 ) / 90 = 141 / 90 = 47 / 30

17,3 ( 24 ) = ( 17324 - 173 ) / 990 = 17 151 / 990 = 5 717 / 330

0,2 ( 3 ) = ( 23 - 2 ) / 90 = 21 / 90 = 7 / 30

3, 0 ( 24 ) = ( 3024 - 30 ) / 990 = 2 994 / 990 = 998 / 330 = 499 / 165

4 005 / 1 000 = 801 / 200

72, ( 15 ) = ( 7215 - 72 ) / 99 = 7 143 / 99 = 2 381 / 33

2,75 = 275 / 100 = 55 / 20 = 11 / 4

Answer 2

○1,(3)=(13-1)/9=12/9=4/3
