Answer 1

Remember that a rational number is a number that is expressed as the ratio of two integers. According to this, note that:

`0.71711711=(398)/(555)`

but, It is an irrational number because it is not ending and is not repetitive.

`0.0505505550\text{ =}(10110111)/(200000000)`

and

`0.626262626262=(101009971)/(161290115)`

and

`4.8=(24)/(5)`

on the other hand:

`3\text{ = }(3)/(1)`
