**South Carolina Education Standards & Learning**. What Is Percent? A percent is a term that describes a decimal in terms of one hundred. Percent means per hundred. Percents, fractions and decimals all can equal each other, as in the case of 10%, 0.1 and 1/10. Percents can be greater than 100% or smaller than 1%. A markup from the cost of making an item to the actual sales price is usually greater than 100%. A salesperson's commission might be 1/2% depending on the item sold. Read More...

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.2e. Understand that some rational numbers can be written as integers and all rational numbers can be written as fractions or decimal numbers that terminate or repeat.

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

7.NS.5. Extend prior knowledge to translate among multiple representations of rational numbers (fractions, decimal numbers, and percentages). Exclude the conversion of repeating decimal numbers to fractions.

SC.7.RP. Ratios and Proportional Relationships

7.RP.3. Solve real-world and mathematical problems involving ratios and percentages using proportional reasoning (e.g., multi-step dimensional analysis, percent increase/decrease, tax).

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.
