Equivalent Fractions
Some fractions may 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 finest to show response using the simplest fraction ( 1/2 in this situation ). That is dubbed Simplifying, or Reducing the fraction
Numerator / Denominator
We contact the top number the Numerator, that is the variety of parts we have.We call the bottom number the Denominator, the is the number of parts the whole is divided into.

You just need to remember those names! (If girlfriend forget just think "Down"-ominator)
Adding Fractions
It is simple 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) | |||
+ | = | = |
Another example:
5/8 | + | 1/8 | = | 6/8 | = | 3/4 |
+ | ![]() | = | ![]() | = | ![]() |
Adding fractions with different Denominators
But what around when the denominators (the bottom numbers) space not the same?
3/8 | + | 1/4 | = | ? |
+ | = | ![]() |
We should somehow make the denominators the same.
In this situation it is easy, because we know that 1/4 is the very same as 2/8 :
3/8 | + | 2/8 | = | 5/8 |
+ | ![]() | = |
There are two well-known methods to do the denominators the same:
(They both work-related nicely, use the one girlfriend prefer.)
