(A) Recognize that dividing by a rational number and multiplying by its reciprocal result in equivalent values6.10.A
(A) Model and solve one-variable, one-step equations and inequalities that represent problems, including geometric concepts
(Y7) Extend and apply the laws and properties of arithmetic to algebraic terms and expressions (ACMNA177)ACMNA179
(Y7) Solve simple linear equations (ACMNA179)
7.NS.2.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.
