Proportional Relationship 2. Scale Drawing 3. Percent decrease 4. Percent error A. A rate is a ratio involving two quantities measured in different units. B. Ratios that are equivalent. C. The percent a quantity decreases from its original amount (original amount - new amount / original amount) D. Ratios that are equal. 5. Percent Increase E. The rate for one unit of a given quantity 6. Ratio WARM UP F. A fraction that contains a fraction in its numerator or 7. Equivalent Ratios 8. Rate 9. Percent denominator (or in both) G. The percent a quantity increases from its original amount (new amount - original amount / original amount ) H. Is a ratio that compares a length in a scale drawing to the corresponding length in the actual object. 10. Unit Rate I. A comparison between two numbers. 11. Constant of Proportionality J. The percent that an estimated amount is different from the 12. Complex Fraction actual amount K. The unit rate in a proportional relationship L. A ratio comparing a number to 100 (Per 100) 7.RP.1, 7.RP.2, 7.RP.3 1. Opposites 2. Reciprocal 3. Terminating Decimal 4. Commutative Property 5. Repeating Decimal 6. Subtraction Rule A. A decimal that repeats a digit or group of digits forever. B. The distance a number is from zero on the number line. Always positive. Ex. |-5| = 5 C. The property that says that two or more numbers can be added or multiplied in any order without changing the result. D. Another word for additive inverse. A number plus its opposite equals zero. E. Changing the grouping of terms when adding or multiplying does not change the answer 7. Order of Operations 8. Distributive Property 9. Additive Inverse F. A fraction inverted (flipped upside down) - the reciprocal of 2/ 3 is 3/ 2 - also its multiplicative inverse (product is 1) WARM UP G. A decimal that ends H. a(b + c) = ab + ac 10.

Subtracting is the same as adding the opposite of a number (keep, change, change). Ex. 1 - 4 = -3 and 1 + -4 = -3 K. Another word for reciprocal.

Equation 2. Two-step equation 3. Isolate a variable 4. Coefficient A. A mathematical sentence with less than, greater than, less than or equal to, greater than or equal to, or not equal B. A number without a variable - a number that stands alone in an expression or equation. Ex. 4x + 5 - 5 is the constant C. Perform all operations to leave a variable alone on one side of the equal sign - solve an equation 5. Variable D. A mathematical phrase that contains operations, numbers, 6. Expression 7. Simplify an expression 8. Inequality 9. Factor an expression and/or variables. Ex. 3x + 4x + 7 E. The number part of a term with a variable - a number being multiplied by a variable.
