Here is a simple and very useful tool - a free online fraction calculator that does addition, subtraction, multiplication, and division of 2 fractions.

It can even reduce the result to the lowest terms.

Of course, every calculator in the world is suppose to save you time, but using it only makes sense if you already know what it does for you. :-)

So practice enough without a calculator to know how to do a particular problem, even better - master it, then don't waste your time anymore and use calculators.
