Questions and Answers

What is the correct method to find the percentage of the total marks in a test?

  • Add total marks and maximum marks and divide by 100
  • Divide total marks by maximum marks and multiply by 100 (correct)
  • Subtract maximum marks from total marks and divide by total marks
  • Multiply total marks by maximum marks and divide by 100
  • What can lead to confusion for students when understanding percentages?

  • Lack of clarity about the distinction between a denominator and a numerator (correct)
  • Confusion about addition and subtraction
  • Difficulty in memorizing formulas
  • Inability to understand multiplication
  • In the example of traveling 550 miles measured in hundreds of miles, what would be the percentage of the distance traveled?

  • Total number of hundreds divided by 550
  • 550 out of the total number of hundreds in the journey (correct)
  • 550 divided by the total number of hundreds in the journey
  • 550 multiplied by 100

    Study Notes

    • We are starting today's topic in Siks Standards Mathematics and the topic is about Kahneman's students finding it difficult to understand the concept of percentages.
    • The problem lies in the fact that for the students, the distinction between a denominator and a numerator is not clear. This confusion leads to children feeling perplexed as to what percentages are and how to use them.
    • To mitigate this issue, Kahnment explains that if a team of 725 went to a game, and 550 had tickets, the percentage would be what fraction of the total number of people in the stadium made up the team.
    • In another example, if a friend of yours earned 50 dollars and then spent 25 dollars on peppermints, the percentage of the budget spent on the peppermints would be 25 out of the total number of dollars spent.
    • To find the percentage of the total marks you got in a test, you need to divide your total marks by the maximum marks possible and then multiply by 100.
    • In a given example, if you traveled 550 miles and the distance was measured in handreds of miles, the percentage of the distance traveled would be 550 out of the total number of handreds in the journey.
    • Kahneman also mentions that memorizing formulas is not necessary as the concepts can be learned through examples and practice.
