gente me ajudem!!

Answer 1

Resposta:

Explicação passo-a-passo:

a)  0,2333... = 23-2\90 = 21\90 = 7\30

b)  12,515151... = 12 + 51\99 =

12.99+51\99 = 1239\99 = 413\33

c)  5,14343434... = 5 + 1434-149900 = 5 + 1420\9900 =

5.9900+1420\9900 = 50920\9900 =

10184\1980 = 5092\990 = 2546\495

d)  2,35777... = 2 + 357-35\900 = 2 + 322\900 =

2.900+322\900 = 2122\900 = 1061\450

e)  0,1222... = 12-1\90 = 11\90

f)  5,23 = 5 + 23\99 =

5.99+23\99 = 518\99

g)  2,485 = 2 + 485\999 =

2.999+485\999 = 2483\999
