Question

a number written in the form of p upon Q is a rational number if p and q are both integers and P is not equal to zero Q is not equal to zero

Answer 1

yes... a number written in the form of p/Q is a rational no. if p and Q both are integers and Q is not equal to zero.

Answer 2

A number that can be written in the form of p by q where p and q are co prime integers and q not equal to zero is known as a rational number.

p may be 0 in case of a rational number but q cannot be 0.For e. g. 0/3 is a rational number but 3/0 is not because it suggests infinity.
