Remember that of means multiply in mathematics. of = x

3
Key Concepts: One Equation can help you solve each type of problem part=Perce nt Whol e Plug in the pieces of data the problem gives you Your unknown becomes your variable

4
Key Concepts: part=Perce nt Whol e What percent of 80 is 25? 25 = p 80 25 = 80p 25 80 80p 80 = 31.25% = p

5
Key Concepts: part=Perce nt Whol e 30% of what number is 120? 12 0 =.30 w 120 =.30w 120.30.30w.30 = 400 = w

6
Key Concepts: part=Perce nt Whol e What is 85% of 150? p =.85 150 p = 127.5

7
Practice: part=Perce nt Whol e The length of the Appalachian Trail is 2174 miles. 25% of the length is in the state of Virginia. How many miles are in Virginia? p =.25 217 4 p = 543.5 miles are in Virginia

8
Practice: part=Perce nt Whol e There are currently 130,000 nurses in the state of Florida. Of those nurses, 34,000 are new. What is the percentage of new nurses? 34,00 0 = p 130,00 0 34,000 = 130,000p 34000 130000 130000p 130000 = 26.15% = p

9
Practice: part=Perce nt Whol e 15 is 2.5% of what number? 15 =.02 5 w 15 =.025w 15.025.025w.025 = 600 = w

10
Practice: part=Perce nt Whol e What is 52% of 260? p =.52 260 p = 135.2

11
Practice: part=Perce nt Whol e What percent of 280 is 157? 15 7 = p 280 157 = 280p 157 280 280p 280 = 56.07% = p

12
Finding Percent (Part) of a Whole: Method Two: Write an EquationFind 15% of 56 Change percent to decimal and of to multiplication.15 x 56 Multiply = 8.4.15 x 56

13
Finding Percent (Part) of a Whole: Method Two: Write an EquationFind 32% of 75 Change percent to decimal and of to multiplication.32 x 75 Multiply = 24.32 x 75

14
Practice: part=Perce nt Whol e 60 is 48% of what number? 60 =.48 w 60 =.48w 60.48.48w.48 = 125 = w

15
Practice: part=Perce nt Whol e 24 is 65% of what number? 24 =.65 w 24 =.65w 24.65.65w.65 = 36.92 = w

16
Practice: part=Perce nt Whol e 42 is what percent of 60? 42 = p 60 42 = 60p 42 60 60p 60 = 70% = p

17
Practice: part=Perce nt Whol e 110 is what percent of 200? 11 0 = p 20 0 110 = 200p 110 200 200p 200 = 55% = p
