Answer:
Given: Let x and y be positive integers
Explain why it is incorrect to claim that x/√y is always irrational
Example: Let x = 5, and y = 9.
5/√9=5/3=1.6
Given: 0<A<B
Explain why it is correct to claim that A/B<B/A is true,
It is shown that A/B will always be < 1, and B/A will always be > 1.
Step-by-step explanation:
Rational numbers are numbers that can be written as a fraction of integers. To explain why this statement is incorrect, consider using a perfect square. A perfect square is a number that can be expressed as the product of two equal integers (9, 16, 25…), where y is the perfect square.

-n is always less than zero because every variable is always equal to one unless having a substitution so -n would be equal to -1.
