Doing it that way you can't. One is a string, the other's a number. You'd
have to first convert the fraction into it's decimal representation. You
could prolly write a function to do that. Something like this would work:
str = '3/8';
function convertDecimal(str) {
arr = str.split('/');
return arr[0] / arr[1];
}
alert(convertDecimal(str));

Subject: Simple JS math?
Looking to add an integer and a fraction. How do I do this with Javascript?
Thanks, Che!
<script language="JavaScript">
var num = 20;
var frac = "3/8";
var DBWTemp = (num + frac);
document.write(DBWTemp);
</script>
