fiddle:

function update($ele) {
    var n = Number($ele.find('.numerator')[0].value);
    var d = Number($ele.find('.denominator')[0].value);
    /* this works but is slightly more verbose (and maybe a bit slower) */
    var val = (n / d * 100);
    $ele.find('.result').text(( isNaN(val) || ! isFinite(val) ) ? '' : val.toFixed(2));
    /* This might be faster, and also make everything a bit more succinct * /
    var val = d !== 0 ? n / d * 100 : NaN;
    $ele.find('.result').text(isNaN(val) ? '' : val.toFixed(2));
    /* */
}
