Question

Dê a fração geratriz :
2,888 ...
5,2323
4,1222..
3,29191

Answer 1

10×= 28,888... ×= 2,888... 9×= 26 ×= 26/9 (forma fracionária)

Answer 2

2,888... = 2 + 0,888...    2 + 8/9 = (2.9 + 8)/9 = 26/9 

5,232323... = 5 + 0,232323... = 5 + 23/99 = (5.99 + 23)/99 = 518/99

4,1222... = 4 + 0,1222... = 4 + (12 - 1)/90 = 4 + 11/90 = (90.4 + 11)/90
(360 + 11)/90 = 371/90

3,29191919... = 3 + 0,2919191... = 3 + ( 291 - 2)/990 = 3 + 289/990

(3 . 990 + 289)/990 = (2970 + 289)/990 = 3259/990
