This math topic focuses on adding fractions, particularly those that require a common denominator. It involves problems where one or both fractions have their denominators changed to facilitate addition. Skills practiced include converting fractions to equivalent fractions with a common denominator and then adding the fractions correctly. The problems are structured with multiple-choice answers, allowing practice in not only performing the addition but also verifying the accuracy of the resulting fractions against possible solutions.
