Question

What fraction represents 0.64 ?
A : 64/9999
B : 64/999
C : 64/99
D : 64/9

Answer 1

I think c is the right answer

Answer 2

Answer: C. 64/99

I think the decimal given is recurring, 0.6464…

let for ones, be x

`100x = 64.6464 - - - (i) \\ x = 0.6464 - - - (ii)`

subtract (ii) from (i):

`99x = 64 \\ \\ { \boxed{ \boxed{x = (64)/(99) }}}`
