This is the vLite version of Das Telefon's "Basic Fractions". The vLite version contains a small fraction(!) of what is available in the full version. The description below is from the full version of the application.
Many different techniques can be adopted to solve fractions. Using some such techniques - and active user involvement - Basic Fractions will show the user how to add, subtract, multiply and divide normal and improper fractions.
The application is split into four categories (Addition, Subtraction, Multiplication and Division), and there are a total of 70 questions.
At the bottom of the screen for each question is a list a numbers from which the user 'drags and drops' the answers into the highlighted answer location. Once the correct/acceptable answer is 'dropped', the next answer location will become available. This continues until the question is completely answered.
Basic Fractions contains context-related help screens; offering help relevant to where the user is at that point.
Basic Fractions covers normal and improper fractions, but does not simplify the answers (e.g., into whole numbers and fractions).
