Answer:

Natural, Whole, integer, rational, real

Step-by-step explanation:

Here, the given number,

\(\frac{121}{\sqrt{121}}\)

We can write,

\(\frac{121}{\sqrt{121}}=\frac{121}{11}\)

∵ 121 and 11 are integers also, 11 ≠ 0,

So, \(\frac{121}{11}\) is a rational number,

⇒ \(\frac{121}{\sqrt{121}}\) is a rational number,

Now,

\(\frac{121}{11}=11\)

11 is a whole number,

⇒ \(\frac{121}{\sqrt{11}}\) is a whole number,

Again, a whole number is always a natural number and a positive integer ,

⇒ \(\frac{121}{\sqrt{11}}\) is a natural number or an integer,

All numbers ( rational or irrational ) are called real number.

So, we can also write,

\(\frac{121}{\sqrt{121}}\) is a real number.
