There are three steps to reading fractions on a
number line
  • Step One-Count the spaces in between the zero and
    the one on the number line. That is your
    denominator.

There is only a step three if the fraction is
past a whole number.
  • If the fraction is past a whole number, steps one
    and two are the same except that you count the
    spaces and marks in between the whole numbers
    closest to the fraction.
