Why use Fractions?

A Fractions is used to discuss PART OF A WHOLE!

Suppose someone offered you some pizza.
Your answer will determine how much you get.
"Do you want pizza?"
YES, BUT HOW MUCH?
1) "ONE" - you will get a WHOLE pizza.
2) "one-half" = "1/2" will get you a half of pizza.
(ONE PIZZA CUT INTO TWO EQUAL PARTS -
YOU WILL GET ONE OF THESE PIECES)
3) "two-thirds" = "2/3" might need a picture to represent.
First ONE PIZZA will be cut into 3 EQUAL PARTS
and then you will get 2 OF THESE EQUAL PARTS.


Bythe way, if the pizza is cut into
12 equal parts and you eat 8 parts
that is the same as 2/3.












Thus, the conclusion about a fraction:
The DENOMINATOR (Bottom)
represents the number of equal
parts in which that item (PIZZA) is to be cut.
The NUMERATOR (Top) represents the number of these parts that you want to have (to consider, to focus on, to use, to ...).

4) What would 5/8 get you?
The denominator says to cut it (the "ONE WHOLES" pizza) into 8 EQUAL PARTS
and then you get the number of these EQUAL PARTS - that is in the numerator, 5.
