Answer:
i don't know the sums of a and b so hope this helps
Step-by-step explanation:
Actually, the sum of two rational numbers can be either rational or irrational, depending on the specific values of the two numbers.
For example, if a = 1/2 and b = 1/3, then a + b = 5/6, which is a rational number.
However, there are cases where the sum of two rational numbers is irrational. One such example is when a = 1 and b = -1, in which case a + b = 0. The number 0 is neither positive nor negative, and is therefore not a rational number.
In general, the sum of two irrational numbers is not necessarily irrational. For example, √2 + (-√2) = 0, which is rational.
Therefore, we cannot conclude that a + b is irrational without knowing the specific values of a and b.
