Hi there !!

we know,


$\frac{1}{2} = 0.5$

$\frac{2}{3} = 0.66666...$

Since there are infinite set of IRRATIONAL numbers between two RATIONAL numbers ,

we can take any number just we need to make sure that it lies in the given range which in this case is 0.5 or 0.5000 and 0.6666

So,
One of the possible irrational number between
1/2 and 2/3 can be 0.514598655736....


POINT TO BE REMEMBERED
Just know that the number you use will lie in the given range and should be non terminating (endless) and non recurring (non repeating )


Hope it helped you :-)
