(6) Improper Fraction.
This is a fraction having a numerator that is
equal to or greater than its denominator. It is either a whole number or a
whole number and a fraction of another whole number. For example, 4/4 may
be expressed as 1, or 3/2 may be expressed as 1 + 1/2.
(7) Value of a Fraction. This is the number that the fraction represents.
From the diagrams in figure 3, it can be readily seen that 1/2 in a, 2/4 in
b, 4/8 in c, and 6/12 in d are all equal in value, even though the terms of
each succeeding fraction are greater than the terms of all the previous
fractions.
But if the fraction 6/12 was increased by the fraction 1/12,
then 6/12 plus 1/12 would equal 7/12, and the value of 7/12 would be greater
than the value of all the previously mentioned fractions.
