How to convert decimal to fractions?

Question

What I need to convert decimal to fractions. It is easy to convert to 10\'s feet.

1.5 => 15/10

This can do via this code:

Answer 1

Here is a simple algorythme :

numerato = 1.5
denominator = 1;

while (!isInterger(numerator*denominator))
do
    denominator++;
done

return numerator*denominator + '/' + denominator


// => 3/2

You just have to implement it in java + implement the isInteger(i) where i is a float.
