But, I would like the output 1.3 as value in the last column of above output as below:
-- select v4.count_v2 from v4 -- 8
-- select v3.count_v1 from v3 --6
select round(8/6,1) from dual -- 1.3
I have included create Table (Insert/Structure) statements

The value of COUNT(V3.COUNT_V1) is 8, not 6, therefore the result is 1, not 1.3, as demonstrated below.

Perhaps this is what you want instead, using just Round(v4.count_v2 / v3.count_v1, 1) without the extra counts and adding them to the grouping.

You could go with an inline selectWITH

But what bothers me is what you do in "V". Since you will never get Results from V1 you can just select everything from V2 in your last statement:WITH
V1(TOLL_ID, ENTRY_PLAZA, EXIT_PLAZA, PLATE, TOLL_DATE) AS
(SELECT 1, 101, 102, 'MARS01234', TO_TIMESTAMP('21.04.2017', 'DD.MM.RRRR') FROM DUAL

I assume that you might want to exclude the rows from V1 which have a match in V2 but the matching criteria is not clear. If it's V2.VIOLATION_ID = V1.TOLL_ID this might help:WITH
