So, the first thing we need to know is what is what.
So, A natural number is a whole number
A whole number is an integer
and An integer is a rational number.
Now, since there is a terminating decimal (a decimal that does not go on forever) we know it is a rational number.
Since there is a decimal, it cannot be an integer, therefore
It is a rational number
9 : 2 = 18 : 4
As: 9 x 2 : 2 x 2 = 18 : 4
--------------------
36 : 8 = 18 : 4
As: 18 x 2 : 4 x 2 = 36 : 8
--------------------
72 : 16 = 18 : 4
As: 18 x 4 : 4 x 4 = 72 : 16
Not sure, there is no graph with it. I just edited the question to fix the formatting and to add in info that got cut off when iI pasted it in.
I can’t remember the answer but I learned that a while back
