Question 93
If x and y are two rational numbers such that x > y, then x - y is always a positive rational number.

Answer 1

True
If x and y are two rational numbers such that x > y
Then, there are three possible cases, i.e.
Case I: x and y both are positive
Case II: x is positive and y is negative
Case III: x and y both are negative
In all three cases, x - y is always a positive rational number.
