HW #8  Due on November 22, 2021

  • 2.1:  1 – 75 odd.  [Make sure you make neat diagrams]
  • 2.3:  1 – 75 odd.  I do have some different instructions.  Please read below.

For problems 17 – 23, reduce each fraction to see if they are equal.  Please do not cross multiply.

For problems 61 – 67, first cancel as many zeros that match up in numerator and denominator.  For example if a numerator is 2400 and a denominator has 36000, then you can cancel two zeros in numerator and denominator.  You would be left with 24 over 360.  You then follow the steps from class and factor each number, cancel, etc.

Please remember to put in a one fir all factors cancel in either the numerator or denominator.  If a fraction has one in the denominator at the end, divide numerator by one which will just be the numerator.

I will try and get some examples for the above sections on words.
