Dividing the numbers.

I don't think that's the answer you are looking for, but I have no idea what the real question is.

You need to multiply or divide (EXCLUSIVE OR) the ratio by 1 so that each part is a natural number, or as close to natural numbers as reasonably possible.

I am sure that's not what you have aimed at. Multiplying or dividing by 1 doesn't change the situation :wink:

My first idea was too that sweet should look for integer ratio, but numbers shown (283/503) lead nowhere.

1 is a rational number which can be expressed as N/N for any real number N.

I did not actually try to solve the original poster's question; only offered a commonly used suggestion. If he is trying to process experimental measurements, some of the data could have errors, even somewhat small errors.
