About Fraction Calculator
Punch in a fraction, choose your operation, and get a clean result — including the simplified form — in seconds. Whether you're checking homework, scaling a recipe, or working through a construction measurement, this calculator handles the arithmetic so you don't have to wrestle with lowest common denominators by hand. It works with mixed numbers too, not just simple fractions.
It's part of a growing set of math and productivity tools on Launch Arcade. If you need to go further with numbers, Statistics Calculator is a natural next step for anyone dealing with data sets alongside fractional values.
The interface is keyboard-friendly, so power users can move through inputs without touching the mouse — handy if you're working through a long list of calculations at a desk.
