Answer:
1). Rational
2). Irrational
3). Rational
4). Rational
5). Irrational
Step-by-step explanation:
To solve this question we should follow the rule,
"Addition of rational and an irrational number is an irrational number."
1). (rational number)
(negative rational number)
[rational number]
2). π → (Irrational number)
24 → (rational number)
π + 24 → (Irrational number)
Since addition of a rational and an irrational number is an irrational number.
3). = 2 (rational number)
5 (rational number)
2 + 5 = 7 (rational number)
4). (rational number)
(rational number)
(rational number)
5). (rational number)
→ (Irrational number)
→ (Irrational number)
