There is more than one way to determine a sum. Scholars demonstrate their understanding of the decomposition of fractions similar to the decomposition of whole numbers. The short task requires pupils to determine which sums of fractions with common denominators equal a given fraction. After finding the different equivalent sums, individuals come up with a sum on their own.
