What KBruch is
KBruch is a free program for practicing fraction and percentage calculations. It checks each answer and provides feedback, while a learning mode focuses on fraction practice. Exercises cover several kinds of work: solving a fraction task by entering a numerator and denominator, comparing two fractions with greater-than, less-than, or equals signs, converting a number into a fraction, and expressing a number as its prime factors. A separate exercise asks users to calculate percentages. KBruch is listed for Linux, macOS, and Windows. Linux installation is available through Discover or another AppStream application store, a distribution package manager, or Flathub; nightly installers are offered for macOS and Windows. The project lists the GPL-2.0+ license and links to the KBruch Handbook, UserBase Wiki, KDE Forum, and kde-edu mailing list. Version 26.08.2 is listed, released on 2026-10-08.
