Onmatu- Arithmetic Article


If someone is hungry better leave reading this article for this moment :). Why I said that? 
Usually in math textbooks fractions are explained using PIZZA example. :)
Should I do the same...

So, we imagine ONE pizza in front of us. Then we cut it to pieces. Let's say 2 pieces of the same size. 
If you share this pizza with your friend, you will take one piece or ONE HALF of the pizza.

We write ONE HALF as
Your friend took another piece which is again 1/2 of the pizza.
                         1/2 + 1/2 = 1.
On the other hand, if we cut our pizza to 3 
pieces of the same size and you take one piece, this is 1/3 of the pizza. If you take two pieces, this will be 2/3 of the pizza. Therefore,
                      1/3 + 1/3 = 2/3 and

                  1/3 + 1/3 + 1/3 = 1.
You can regonize a "pattern" now. If we have four equal pieces it will be 

            1/4 + 1/4 + 1/4 + 1/4 = 1,

and so on.
