Decimal Operations

SC.7.NS. The Number System

7.NS.2. Extend prior knowledge of operations with positive rational numbers to multiply and to divide all rational numbers.

7.NS.2c. Understand sign rules for dividing rational numbers and that a quotient of integers (with a non-zero divisor) is a rational number.

7.NS.3. Apply the concepts of all four operations with rational numbers to solve real-world and mathematical problems.

SC.7.EEI. Expressions, Equations, and Inequalities

7.EEI.3. Extend previous understanding of Order of Operations to solve multi-step real-world and mathematical problems involving rational numbers. Include fraction bars as a grouping symbol.

7.EEI.4. Apply the concepts of linear equations and inequalities in one variable to real-world and mathematical situations.

7.EEI.4a. Write and fluently solve linear equations of the form ax+b=c and a(x+b)=c where a, b, and c are rational numbers.

7.EEI.4b. Write and solve multi-step linear equations that include the use of the distributive property and combining like terms. Exclude equations that contain variables on both sides.

7.EEI.4c. Write and solve two-step linear inequalities. Graph the solution set on a number line and interpret its meaning.
