Answer:
Location of an irrational number is an approximate location because irrational number does not yield a specific number or a point on a graph.
Explanation:
The irrational numbers cannot be written as a ratio of integers. Moreover if any number mathematically accept the concept of continuity, then the answer is that we can plot it on a graph, but in the physical world, there is no such thing, so the answer is that we cannot plot it on an exact location and we prefer plotting it on an approximate location.
