Justify decompositions, e.g., by using a visual fraction model. Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation.Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.Record the results of comparisons with symbols >, =, or 1 as a sum of fractions 1/b. Recognize that comparisons are valid only when the two fractions refer to the same whole. Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Use this principle to recognize and generate equivalent fractions. Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size.
