why is 0/0 a indeterminant number

the value of 0/0 is indeterminate because we cannot determine its value.
as x=0/0
==> 0.x =0
which is true for all x values.
so, no particular value can be given to it.

also people say 0/0 or x/0 is infinite but it is a wrong notion.

because infinite is just a very very large number but division by 0 is undefined.
it is undefined because,

x/0 =y
==> x = 0.y
which is true for no number except x=0 so undefined.
