The set of natural numbers less than 20 is finite: {0, 1, 2, ..., 19} has 20 elements.

The set of improper fractions is infinite.

The set of odd numbers greater than 1 and less than 100 is finite: {3, 5, 7, ..., 99} has 49 elements.

Let you = {5, 10, 15, 20, 25, 30, 35, 40}

     A = {5, 10, 15, 20}

     B = {25, 30, 35, 40}

     C = {10, 20, 30, 40}.

Find A  ⋂  C.
