a) 36,8. 368/10= 184/5


B)1,656565...x= 1,656565...100x= 165,656565...
100x= 165,656565...- x= 1,65656565...99x= 164x= 164/99


C)0,9375.x= 0,937510000x= 9375,9375
10000x= 9375,9375- x= 0,93759999x= 9375x= 9375/999



D)0,843. x= 0,8431000x= 843,843
1000x= 843,843- x= 0,843999x= 843x= 843/999


E)7,5818181... x= 7,5818181..10x= 75,818181...1000x= 7581,818181...
1000x= 7581,818181...- 10x= 75,818181...990x= 7506x= 7506/990


F)12,321232/100= 39/25
