Which of the following is the fractional equivalent to 0.78

78/10,

13/49,

39/50,

78/100?

Answer 1

Well, technically, 78/100 is equal to 39/50 and both are equal to 0.78, but to get 39/50 from 0.78 you have to write it as 78/100 first, so the answer is 78/100.

Answer 2

78/100

This can be lowered to 39/50 though...but directly to fraction it would be 78/100

Answer 3

78/100
