Question

\[3 . 27\]  is

पर्याय

• an integer

• a rational number

• a natural number

• an irrational number

Answer 1

We have,

`3.overline27=3.27272727...`

Let 

x=3.27272727....

Then,

`100 x =327 . 272727`

`10000x= 32727.2727...`

Subtract these to get

`9900x= 32400`

`x = (32400)/9900`

`x= 324/99`

Thus, we can also conclude that all infinite repeating decimals are rational numbers.

Hence, the correct choice is (b).
