Question

Sendo a= 0,5666... e b= 0,3444..., calcule o valor de E= a/b - 113/62.

Answer 1

a = 0,5666 . . . = (56 -5)/90
a = 51/90

b = 0,3444 . . . = (34 -3)/90
b = 31/90

a/b = (51/90) / (31/90)
a/b = (51/90) * (90/31)
a/b = 51/31

E = a/b - 113/62
E = 51/31 - 113/62 = 102/62 - 113/62
E = - 11/62
