Answer 1

a) 0,003003003... x=0 1000 X =3 x = 3/999 = ( simplificando ) =1/333 X = 0,003003003... b) 5,018018018... X = 5 1000 x = 5018 999 x = 5013 x = 5013/999 557/111 X = 5,018018018 c) 1,04727272... 100 x = 104 10000 x = 10472 9900 x = 10368 x = 10368/9900 x =288/275 x = 1,04727272... d) 3,61666... 100 x = 361 1000 x = 3616 900 x = 3255 x = 3255/900 x = 217/60 x = 3,61666... e) 2,06818181... 100 x = 206 10000 x = 20681 9900 x = 20475 x = 20475/9900 x = 91/44 x = 2,06818181 f) 1,05333... 100 x = 105 1000 x = 1053 900 x = 948 x = 948/900 x = 79/75 x = 1,05333...
