# Segfrac --- Introduction ---

This module is an exercise destinated to people having already learned the addition of rational numbers with different denominators.

Here we ask the inverse problem: given a rational number $r$, we want to decompose $r$ into a sum of two or more rational numbers, the latter having predetermined denominators.

We guarantee that each question asked has at least one solution. In general, the solution of this kind of question is not unique. And any good solution will be recognized by the software.

Choose the level of difficulty which suits you:
• 1
• 2
• 3
• 4
• 5
• 6
• 7

A higher number corresponds to a higher level of difficulty.
