The peak number claims how countless slices we have. The bottom number claims how plenty of equal slices the whole pizza was cut into.

You are watching: 3/4 plus 1/8

Equivalent Fractions

Some fractions might look different, however 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 solution using the simplest portion ( 1/2 in this case ). That is called Simplifying, or Reducing the fraction

Numerator / Denominator

We call the peak number the Numerator, it is the variety of parts us have.We contact the bottom number the Denominator, the is the variety of parts the totality is divided into.

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

Adding Fractions

It is simple to add fractions v the same denominator (same bottom number):


1/4 +1/4 =2/4 =1/2
(One-Quarter)(One-Quarter)(Two-Quarters)(One-Half)
+==
One-quarter plus one-quarter amounts 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 different Denominators

But what about when the denominators (the bottom numbers) space not the same?


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

We have to somehow make the platform the same.

In this instance it is easy, since we recognize that 1/4 is the exact same as 2/8 :


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

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

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