The height number says how countless slices we have. The bottom number states how many equal slices the whole pizza was cut into.

You are watching: 1/2 plus 1/4 equals

Equivalent Fractions

Some fractions may look different, but are yes, really the same, for example:

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 situation ). That is dubbed Simplifying, or Reducing the portion

Numerator / Denominator

We speak to the optimal number the Numerator, the is the variety of parts we have.We call the bottom number the Denominator, the is the variety of parts the whole is divided into.

You just have to remember those names! (If girlfriend forget simply think "Down"-ominator)

Adding Fractions

It is simple to add fractions through 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 amounts to two-quarters, amounts to one-half

Another example:


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

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

Adding fountain with different Denominators

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


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

We must somehow do the denominators the same.

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


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

There space two popular methods come do the denominators the same:

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