Multiply 4.62 by a number that to get an integer.
Such as multiply by 5 is 23.10 so to get rid of 0.1, just multiply by 50 then it becomes 231.
so that means...
4.62 = 231 / 50
or a simple answer would be multiply by 100, then you get 462.
so....
4.62 = 462 / 100
And then simplify, it is divisible by 2 so the answer is 231/50
