Mixed Numbers as Fractions
uses Circles to demonstrate how a fraction can be renamed from mixed
form to fraction form.
The circles below show the mixed number
2 2/5. You are to write 2 2/5 in fraction form with
only a numerator and denominator.
In the example below, you will notice that
each of the two whole circles has 5 colored pieces and the part
circle has 2 colored pieces, giving 12 colored pieces. 12 is the
numerator of the fraction. Because each circle has 5 equal parts
the denominator is 5, giving a fraction of 12/5. Some textbooks
call a fraction such as this where the numerator is equal to or
larger than the denominator improper. This is also known
as the fraction form or the a/b form of the number.
To write the example, you can think of each
whole number as 5/5. So in the above example you would have:
Another way to arrive at the numerator 12 is
to multiply the whole number 2 by the denominator 5 and then add
the numerator 2 as in this example:
