This topic covers skills related to adding fractions and finding missing values without changing denominators. The focus is on solving equations where one must determine the missing fraction that would make the equation correct. Each problem involves a different set of fractions, but all require understanding of fraction addition and the ability to keep denominators unchanged while solving for the unknown part. This forms part of a broader introduction to fraction addition and subtraction.
