Interactive Math Tutor: KBruch for Fractions and Percentages

KBruch is a Windows application built to strengthen users’ ability to work with fractions and percent values. It’s offered at no cost and provides a selection of practice activities designed for different stages of learning, from beginners to more advanced students. The exercises are presented in a hands-on format so learners can actively solve problems rather than passively read explanations.

Guided practice with instant feedback

The program includes a practice mode that checks answers as you enter them and gives corrective feedback, helping learners identify mistakes and understand the correct procedures. This immediate response loop supports steady improvement and helps solidify key concepts over repeated practice.

Topics and exercise types

• Percentage problems for calculating ratios, increases/decreases, and percent conversions.
• Prime-factor breakdowns to help users decompose numbers into their basic factors.
• Converting whole numbers and decimals into fractional form.
• Comparing two fractions to determine which is larger or whether they are equivalent.
• Tasks that require entering numerators and denominators to solve fraction arithmetic.

Platform, cost, and target users

KBruch runs on Windows and is distributed free of charge. It’s appropriate for students, tutors, and anyone wanting to refresh or refine their fraction and percent skills — useful both for classroom practice and independent study.
