Question

calcule a fação da geratriz de dizimas periodicas compostas 3.1777

Answer 1

x = 3.1777
100x = 317,777
100x = 286 + 31,777
100x = 286 + 10x
100x - 10x = 286
90x = 286
x = 286/90 ÷ 2
x = 143/45

R.: 143/45

x = 5.3111..
100x = 531.111
100x = 478 + 53.1111
100x = 478 + 10x
100x - 10x = 478
90x = 478
x = 478/90 ÷2
x = 239/45

R.: 239/45
