This construction and carpentry fraction calculator takes the hassle out of working with two fractions, including whole numbers. It will perform addition, subtraction, multiplication and division on two fractions for you.

It also reduces the result to the lowest common divisor and provides the decimal value (just in case you may need that too).

This calculator was written for my buddy Mike; who always made construction projects more interesting with his ‘unique’ fraction adding skills.

Whether you’re a professional contractor, handyman, woodworking, or home improvement DIYer, this calculator will make quick work of your fractional measurements. Next time you pull out your tape measure, also keep this calculator handy.
