Common Core Standard 7.RP.3 Monday, December 8, 2014 ‘A’ Week Name: _________________________ Period: _____ 90 56 ? 300 ALL Students who took the test. ALL Girls + ALL Boys who are in the class.

40% 20 ? 40% 20 ? 40 ? Students Percent 30 100 6 20 ÷ 5 What is the part? __________ What is the percent? _________ What is the whole? _________ 20% 30 ?

Art Projects Percent 25 100 5 20 ÷ 5 What is the part? __________ What is the percent? _________ What is the whole? _________ 20% 25 ? Interpreting your answers: There were ___________ art projects turned in by Ty’s Class. ________ % of the ________ art projects received a perfect score. Out of the _______ projects turned in, _________ students received a perfect score. 25 2025 5

Students Percent 30 100 3 10 ÷ 10 What is the part? __________ What is the percent? _________ What is the whole? _________ 70% 30 ? Interpreting your answers: There were ___________ students in Ty’s English class. ________ % of the ________ students completed the essay by the due date. Out of the _______ students who needed to turn in an essay, only _________ students turned in their essay by the due date. **REMEMBER TO USE SIMPLE PERCENTS ( 5% - 10% - 20% - 25% - 50% to simplify )** x 7 70 x 7 21 30 7030 21

The bag contains ______________ pieces of candy. Equation: Part = Percent x Whole Let y = unknown What is unknown at this time? ____________ Therefore, we Label: _________ as y Equation: Part = Percent x Whole Let y = __________ (Part) (Percent ) (Whole) ____________ = ____________ x ____________ Equation: Part = Percent x Whole Let y = __________ (Part) (Change Percent to Decimal ) (Whole) ____________ = ________________ x ____________ Now solve it. Solution: _________________________________________________________ 300 part y 28% 300 part y 0.28 300 y=0.28 x 300, therefore y = 84.Of the 300 pieces, 84 pieces are red.

Equation: Part = Percent x Whole Let y = __________ part Equation: Part = Percent x Whole Let y = __________ (Part) (Change Percent to Decimal ) (Whole) ____________ = ________________ x ____________ Now solve it. Interpreting the solutions from Exercises 1 & 2: part y 0.72 300 y=0.72 x 300, therefore y = 216. (Part) (Percent that is NOT Red) (Whole) ____________ = ________________ x ____________ Simplify. y (100-28)% 300 (Part) (Percent that is NOT Red) (Whole) ____________ = ________________ x ____________ y (72)% 300 Solution: ____________________________________ There were ___________ pieces of candy in total. We have now determined that 28% ( _______ pieces) were red, and the other 72% ( ________ pieces) were NOT red. 300 84 216

Balloons Percent 24 15 8 5 ÷ 3 What is the part? __________ What is the percent? _________ What is the whole? _________ 15% 24 ? **REMEMBER TO USE SIMPLE PERCENTS ( 5% - 10% - 20% - 25% - 50% to simplify )** x 20 100 x 20 160 Equation: Part = Percent x Whole (Part) (Percent ) (Whole) 24 15% y (Part) (Percent as a decimal) (Whole) 24 0.15 y _______ = ________________ x ____________ What is the GCF of 15%? Interpreting the solution: Zoey had inflated ______ balloons, which was only ____% of the balloons in total. If Zoey inflates all of the balloons needed for the school dance, she will inflate ______ balloons in total. 24 15 160
