Answer:
1) The collection of negative numbers and
whole numbers is denoted by
Answer :
→ Negative numbers + whole numbers =
Negative numbers + positive numbers = Integers Denoted by Z.
2) mis
Answer:
• TT is an irrational number.
3) If 'x' is an irrational number, then x + 2 is a/an number.
Answer :
. Irrational + Rational = Irrational.
+ x + 2 = Irrational + Rational Irrational,
4) Numbers which cannot be expressed in p/q
form are
numbers. "
Answer :
. Irrational numbers are the numbers which cannot be expressed in p/q form.

9) Which of the following statements is false?
Answer :
→ Every rational number is a natural number =
False.
➡ Every rational number is a whole number = False.
➡ Every rational number is an integer = False.
Example :- 1/5, 2/3, 8/9 are rational numbers but not integers, natural numbers or whole numbers.
Every integer is a rational number and Every rational number is a real number.
10) Which of the following statements is true?
Answer:
➡ Product of two irrational numbers is always
irrational False. [2√32 = √64=8 = Rational.}
➡ Product of a rational and an irrational number
is always irrational = True.
→ Sum of two irrational numbers can never be irrational = False (√2 + √5=(√2 + √5) is an irrational number.]
→ Sum of an integer and a rational number can never be an integer = False {Since every integer is a rational number. Ex. 5+7= 12 =>
an integer.}
