Many children and
adults are confused by fractions. One aspect of that confusion
comes from an either/or problem: the numerator or the
denominator. Either the number on the top of the line is the
numerator or it is the denominator or the number on the bottom is
the denominator or it is the numerator. For most
people this it not confusing, but for the person who has a
right/left problem, this confusion can persist for a lifetime.
