Which fractions give recurring decimals?
Those whose reduced denominator has a prime factor other than 2 and 5. A seventh recurs forever; an eighth does not.
How do I simplify a fraction?
Divide both parts by their greatest common factor. 48/18 has a GCF of 6, giving 8/3.
What if the denominator is negative?
The sign moves to the numerator, since 5/−10 and −5/10 are the same number. This page normalises it that way.
