To add them, you first need a common denominator.
So multiply <span> 1/4 by 5/5 and 1/5 by 4/4 first. 

Now they'll be 5/20 and 4/20. 

Add them to get 9/20. </span>

subset to real numbers, and as you can see are not at all connected to the rest of numbers (and integers).
Natali5045456 [20]

Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.

The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.

Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.

For example:-

1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, \sqrt{2} is an irrational number but none of the rest.
