Connect percent and proportion

• Use a Proportion to Find the Percent


  • The basketball team statistician tracked the shots Emily made and the shots she missed during the last game. What percent of attempted shots did she make?
  • Camila makes 2 of her 5 shots attempted. Is the percent of shots she made more than, less than, or the same as Emily's percent of shots?
• Use a Proportion to Find the Part

  1. A plan to expand Megan's room will make the length of the room 175% of the current length. What will be the new length of her room?

  2. Megan's room is expanded so the width is 150% of 3 meters. What is the new width?
• Use a Proportion to Find the Whole

  1. The nutrition label shows the percents of the recommended daily intake for nutrients found in a serving of a soy milk. How many milligrams of calcium should you consume each day?

  2. Use the soy milk label in Example 3. What is the recommended amount of iron needed each day? Round your answer to the nearest mg.
• The proportion 75/150 = x/100 can be used to find the whole, w
• 75 is represented by 150%, w is represented by 100%
• w is less than 75 because 100% is less than 150%
• Write a percent proportion for the bar diagram shown

  17 = x/100
• Use a proportion to find each value

  • 2% of 180
  • What percent is 17 out of 40?
