Answer:
We need some numbers to work with to truly answer this. However here's a definition of a rational numbers
A rational number is any number that isn't infinite and non-repeating. So decimals, fractions, repeating numbers/decimals like 1.535353.... (53 is the "pattern") are all rational and fair game. Numbers like pi (π), "imperfect" square roots, etc. that don't repeat and are infinite or NOT RATIONAL.

As a fraction it is 16/9 and for a decimal it is 1.7777 repeating
This one is easy all you have to do is subtract the 2.25 by the 15 to get 12.75.
4 and 6!
4*6 = 24
24 - 14 = 10
4 + 6 = 10
