## ◂Math Worksheets and Study Guides Seventh Grade. Introduction to Percent

### The resources above correspond to the standards listed below:

#### Maryland College and Career-Ready Standards

MD.MA.7.RP. Ratios and Proportional Relationships (RP)
Analyze proportional relationships and use them to solve real-world and mathematical problems.
7.RP.3. Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
7.RP.3.1. Ability to build on prior experience with equivalent fractions to solve multi-step problems with ratio and percent (see 6.RP.3c).
MD.MA.7.EE. Expressions and Equations (EE)
Solve real-life mathematical problems using numerical and algebraic expressions and equations.
7.EE.3. Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically; apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making \$25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or \$2.50, for a new salary of \$27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.
7.EE.3.1. See the skills and knowledge that are stated in the Standard.
