M.7.Q.NS.2
PriorityEfficiently, flexibly, and accurately apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
- a.Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (-1)(-1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
- b.Understand integers can be divided as long as the divisor isn't zero, resulting in rational numbers.
- c.Apply properties of operations as strategies to multiply and divide rational numbers.
- d.Convert rational numbers into decimals using flexible, efficient, and accurate strategies, recognizing that the decimal form either ends in 0s or repeats eventually.
