  2. PARTS OF A PERCENT PROBLEM • Whole • the total amount • Percent • the fraction of that amount(based on 100) • Part • taken from the whole % of whole is part

  3. Looking for the Percent Example 1: 50 is what percent of 75? Step 1: Identify the information you know. part = 50 whole = 75 percent = ? Step 2: Write the formula and plug in the numbers. Part % 50 % whole 100 75 100 Step 3: Cross multiply 50 x 100 = 5000 5000 75 = 66.7%

  4. Step 2 : part % 12 % whole 100 38 100 Jamie had 38 pieces of candy. She gave 12 to her friend Jordan. What percent of the candy did Jamie give to Jordan? Step 1: part = 12 whole = 38 percent = ? Step 3: 12 x 100 =1200 1200  38 =31.6%

  5. Step 2 : Write formula an plug in the numbers. part % ? 25 % whole 100 80 100 Looking for the Part Example: 25% of 80 is what number? Step 1: Identify the information you know. part = ? whole = 80 percent = 25% Step 3: Cross multiply. 80 x 25 =2000 2000  100 =20

  6. Example: Matthew took 80 foul shots. He made 75% of the foul shots. How many foul shots did he make? Percent= 75% Whole= 80 shots Part= ? 75% of 80 = ? ? 75% 80 100 part % whole 100 75 x 80 =6000 6000  100 = 60 He made 60 foul shots.

  7. Step 2 : Write formula an plug in the numbers. part % 30 60 % whole 100 ? 100 Looking for the Whole Example: 60% of what number is 30. Step 1: Identify the information you know. part = 30 whole = ? percent = 60% Step 3: Cross multiply. 30 x100 = 3000 3000  60 =50

  8. Step 2 : Write formula an plug in the numbers. part % 5 20 % whole 100 ? 100 20% of the class was wearing hats. If 5 students were wearing hats. How many students are there in the class. Step 1: Identify the information you know. part = 5 whole = ? percent = 20% Step 3: Cross multiply. 5 x100 = 500 500  20 =25 There are 25 students in the class.
