About Fraction Drills Free

Having problems learning to work with fractions? Or just want a refresher? This app will help you do that . . . for free!

The available problem types are organized into "levels", so you can start with easier problems, and work your way up to harder ones. There is a "test" mode that lets you test yourself to see how much you have learned.

Available problem types:

level 1:
* simplify (e.g. 4/6=2/3)
* change denominator (e.g. rewrite 2/3 as 4/6).
* convert fraction to mixed number (e.g. 3/2 is the same as 1 1/2)
* convert mixed number to fraction (rewrite 1 1/2 as 3/2).

Level 2:
* add and subtract (same denominator, e.g. 1/6+2/6)
* multiply and divide by whole numbers (e.g. 2/5*2)
* Invert, and answer with a fraction (e.g. 1 / (2/5) = 5/2 )

Level 3
* Multiply and divide fractions
* Invert, and answer with a mixed number (e.g. 1/ (2/5) = 2 1/2)
* Find the least common denominator (e.g., given 1/4 and 5/6, LCD is 12)
* Add and subtract fractions
