Identifying Numerator, Denominator, and Unit

Every fractional measurement needs to contain three pieces of information:So, for example, if I say "three fourths of a cup," then I have three pieces, where each is a fourth part made from a cup. So, "three" is the numerator, "fourths" is the denominator, and "cup" is the unit.
  1. The picture below shows some fractional number of turps.

    a) What is the...
    Unit?Numerator?Denominator?



    b) How would I write this measurement in words?




    c) How would I write this measurement in math?




    d) How would I write, in math, that this amount is the same as three gorfs?




  2. The picture below shows a number line split into pieces.

    a) What is the...
    Unit?Numerator?Denominator?



    b) How would I write this measurement in words?




    c) How would I write this measurement in math?




    d) How would I write, in math, that this amount is seventy two?

  3. A box of paper contains ten reams. I used up seven reams. I want to write that as a fraction of a box.
    a) What is the...
    Unit?Numerator?Denominator?



    b) How would I write this measurement in words?




    c) How would I write this measurement in math?




    d) How would I write, in math, that this amount is three thousand, five hundred pages?
