Percentages are an important part of both math and daily life. We deal with percentages all over the place… Calculating tips, 50% off sales, sales tax, or (dare I mention it in April?) income taxes. All of these areas work with percentages.

This percentage calculator easily allows you to convert a percent to fraction or, in reverse, a fraction to percent. By playing with the various values, you can work out various types of problems (“what percent of a number is some other number” for example), and the spoken-word version of various types of problems is shown in the preview. Working various problems through the calculator will quickly build experience with various types of percentage problems.

Also be sure to check out the various fraction and percentage math worksheets on the site for more practice.

Friends! In this era of polarized political punditry, care must indeed be taken to avoid tarnishing with undeserved negativity the very verbal tools we employ. Even supposing the differences found in our associates, our family members or our beloved (or, not so much) electoral candidates are themselves perhaps less important than they seem (or, perhaps, even more not so much), irrespective of nuance, the words we use may escalate these comparisons to Brobdingnagian proportion, and in doing so toss those loyal lexical minions into the political muck.

I loathe to say that such a fate befalls our dear associate “division” and his close kin, which in political parlance has accumulated such a dreadfully undeserved connotation. Subtraction? So negative. But division, yes, division we need by our side in its purist form. This mighty mathematical sword brings so much to our struggle for the equitable partitioning of cakes and other deserts, the proportional reduction of recipes for the making of optimistically smaller quantities of these and other tasty treats, and, importantly, the required percentage calculation of caloric reduction to target weight loss after over indulgence in what may have ultimately been a non-equitable distribution of said dessert portions.

Indeed, without division, we would all be, colloquially, fat cats.

So, take cautious heed not to bandy about words such as division or divided or divisiveness with abandon lest you too sully the reputation of this fine arithmetical specimen. Instead, share with your friends these shiny new division facts worksheets that are designed to fill an otherwise unnoticed gap in the division content on the site. They will hone your skills with basic division facts grouped by distinct divisors.

And, they’re vastly more fun than watching the primary debates.
