4/8 =2/4 =1/2
(Four-Eighths)(Two-Quarters)(One-Half)

It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is referred to as Simplifying, or Reducing the portion

Numerator / Denominator

Adding Fractions

It is easy to include fractions with the same denominator (same bottom number):


1/4 +1/4 =2/4 =1/2
(One-Quarter)(One-Quarter)(Two-Quarters)(One-Half)
+==
One-quarter add to one-quarter equates to two-quarters, equates to one-half

Another example:


5/8 +1/8 =6/8 =3/4
+

=
*
=
*
Five-eighths plus one-eighth equates to six-eighths, equates to three-quarters

Adding fractions with various Denominators

But what around when the denominators (the bottom numbers) are not the same?


3/8+1/4=?
+=
*
Three-eighths plus one-quarter equals ... What?

We have to somehow do the platform the same.

In this instance it is easy, because we know that 1/4 is the very same as 2/8 :


3/8 +2/8 =5/8
+
*
=
Three-eighths plus two-eighths amounts to five-eighths

There are two famous methods come do the platform the same:

(They both work nicely, usage the one you prefer.)
