  1. How to convert a terminating decimal into a rational number of the form (p over q) - Number theory
      Flip
    • << Stop >> Please put the topic into your summary form. Stop and think about what we are gong to do.....what does a terminating decimal? What is a rational number look like?
      Flip
    • Remember, the definition of a rational number is a number that can be written as a fraction. So a terminating decimal is a rational number....we are just putting it in fractional form.
      Flip
    • << Stop>> You may need to add to your notes some of what he is saying, for instance, you should have written how he knows to add two zeros to the denominator here....by the number of digits in the decimal part of the number.
      Flip
    • He is just simplifying the answer.....all answers in mathematics should be simplified fully.
      Flip
    • Make sure you are getting all three of these examples into your notes. If you don't understand any part of it please email Mr. Venner.
      Flip
    • The number of digits "in the decimal part of the number", that means to the right of the decimal only!!
      Flip
    • He just keeps simplifying the fraction by dividing the denominator and numerator by 2.

  2. Converting a Terminating Decimal to Fractional Form
      Flip
    • Please get this example down also....then we'll try a couple.
      Flip
    • Try the following: Convert these terminating decimals to their fractional form...... 1) 0.58, 2) .0024, 3) 18.72. Then flip this card and check your work.
      1. 1) 29/50, 2) 3/1250, 3) 18 18/25
