Question

A number of the form p/q is said to be a rational number if
(a) p and q are integers.
(b) p and q are integers and q ≠ 0
(c) p and q are integers and p ≠ 0
(d) p and q are integers and p ≠ 0 also q ≠ 0.

Answer 1

A number of the form p/q is said to be a rational number if p and q are integers and q ≠ 0. So,option(b) is correct.

Answer 2

Given: we have given a number of the form p/q

To find: we have to find a number of the form p/q is said to be a rational number if

Solution:

• A number that can be expressed in the form p/q, where p and q are integers and p is nonzero, is called a rational number.
• Addition, subtraction, multiplication, and division of rational numbers are performed in the same way as fractions.
• Rational numbers are closed under the operations of addition, subtraction, and multiplication.

A number of the form p/q is said to be a rational number if p and q are integers and q ≠ 0

Final answer:

Hence the option B is the correct option
