Fractions are a fundamental part of mathematics that we learn in elementary school, yet surprisingly, many adults struggle with them as time goes by. According to recent surveys, about 78% of adults can't accurately reduce fractions to their simplest form, often making common mistakes like dividing only the numerator or forgetting to find the greatest common divisor. This quiz is designed to test your skills in simplifying fractions—reducing them by dividing both the numerator and denominator by their greatest common factor until no further simplification is possible. Whether you're brushing up on basic math for everyday use, like cooking recipes or budgeting, or just challenging yourself for fun, these 40 questions will put your knowledge to the test. Each question presents a fraction to reduce, with four options to choose from. Don't worry if you get stumped; we've included the correct answer and a step-by-step explanation for each one. Dive in and see if you can beat the odds—can you simplify like a pro, or has time eroded your fraction fundamentals? Good luck!
