with fractions, we need to be able to convert the value to a
proportional number so we can add or subtract them.
in the image above, by dividing both the numerator and the denominator
by two reduces 8/16 to 4/8, then 4/8 to 2/4, and finally 2/4
to 1/2. Therefore, we now know that 8/16 = 4/8 = 2/4 = 1/2.
We could have easily gone in the other direction, multiplying
both the numerator and the denominator by two never completing
the task since both parts of the fraction would go to infinity.
Class CAD, we use computer applications to solve every type
of challenge. Working with fractions is just one.
