I found how it works, and it doesn't put it into a mixed number. I work on
it this week and see if I can't fix it. Thanks for all the help people!

how about you try it to see what happens, and maybe learn how it works

Would this also print out as a mixed number if it should?

Well how would you do it on paper?
$numerator = 8;
$denominator = 12;
$factor = 1;
//Start at the greater of the 2, and loop down til you find a common
factor
for ($i=max($numerator,$denominator);$i>1;$i--) {
//Check if each number divided by $i has no remainder
if (($numerator % $i) == 0 && ($denominator % $i) == 0) {
//Factor Found
$factor = $i;
break;
}
}
//Now a factor is found, divide by it
$numerator = $numerator / $factor;
$denominator = $denominator / $factor;
echo $numerator . '/' . $denominator;
The method might look like the above

But how do you find it in PHP?

Just like math...find the greatest common denominator of the
numerator
and denominator and then divide each (numerator and denominator)
by
that
number...
ie: numerator = 8 and denominator = 12
so we have 8/12
then greatest common denominator is 4...
so 8/4 = 2 and 12/4 = 3
thus, 8/12 => 2/3

:-P
My problem is this. I want to simplify a fraction to simplest
form
but
if I divide, I'll get a decimal which I can't use. How could I
put
it
in simplest form without displaying a decimal to the user and if
one
does come up, a mixed number?
Thanks,

I use this to convert a decimal stored in a table.
function Fraction ($width)
{
list ($whole, $numerator) = explode ('.', $width);
$denominator = 1 . str_repeat (0, strlen ($numerator));
$GCD = GCD ($numerator, $denominator);
$numerator /= $GCD;
$denominator /= $GCD;
If ($numerator==0) {
return sprintf ('%d',$whole);
} else {
return sprintf ('%d %d/%d',
$whole, $numerator, $denominator);
}
}
function GCD ($a, $b)
{
while ( $b != 0)
{
$remainder = $a % $b;
$a = $b;
$b = $remainder;
}
return abs ($a);
}
So...
$width = 64.75;
Fraction($width);
Results:
64 3/4
You can add <sup></sup> and <sub></sub> for added effect.
