For each problem, add the two fractions. After adding the fractions, type in the numerator and denominator. Use the TAB and the SHIFT+TAB keys to move between numerator and denominator, and from problem to problem.
After adding the fractions and typing in answers for all 10 problems, check your answers. Be sure each answer is simplified to its lowest terms. When you think they are all correct, press the 'Grade My Quiz' button. Your quiz grade will be
