**NCERT Solutions** of Rational Numbers Class 8
# Rational Numbers

Any number which can be expressed in the form of p/q, or number in the form of p/q; where q â‰ 0 is called rational number.

For example

Since, q can be equal to 1, thus, all integers can be expressed in the form of p/q, hence, all integers are also rational number.

As, 0 (zero) is also an integer, hence, 0 (zero) is also rational number.
