The Ratio and Percentage Quiz is a free web app for practicing ratios and percentages in a simple 4-choice quiz format.
It covers percent-decimal conversion, Japanese rate units, finding the rate, finding the compared amount, finding the base amount, discounts, markups, graphs, and exam-style percentage problems.
Students can focus on one skill at a time, then move to mixed practice and advanced entrance-exam style courses.
The quiz helps learners avoid common mistakes such as forgetting to divide by 100, confusing discount amount with sale price, or reversing the base and compared amount.
The course lineup includes short basic practice, topic-based courses, graph questions, and advanced questions involving discounts, profit, concentration, and changing bases.
My Page stores challenge history, best records, and often missed percentage questions, making it useful for daily review.
