                                                                        Numerator
                             1 out of 6 equal sections of a circle is
                                                                        Denominator
Equivalent fractions are fractions with the same value.
                                                          X4
Example :                                 x2         x3

A Mixed Number consists of a whole number and a fraction.
                1           4       1
Example : 1 , 2 , 7
                3           5       4

A proper fraction has numerator that is smaller than its denominator.
            3       3   2       4
Example : 5 , 4 , 7 , 5

An improper fraction has a numerator that is equal or bigger than its denominator.
            5       4 7     2
Example :       , , ,
            5       3 6     2

An improper fraction can be changed into a mixed number

Example :
                                            2
 11                 1
        =2                              5   11
  5                 5                       10
                                            1
Addition and subtraction can be implemented to fractions with common denominator

Example :

1    3      4
    + 7=
7           7
