Find the incorrect option (Assume conventional notations).(a) Q = p/q

1.	Find the incorrect option (Assume conventional notations).(a) Q = p/q where p and q are integers and q=0(b) N = {1, 2, 3…}(c) W = {0, 1, 2, 3…}(d) Z = {…-2, -1, 0, 1, 2…}The question was asked in examination.This interesting question is from Number Systems Basics topic in section Number Systems of Mathematics – Class 9
Answer» Right answer is (a) Q = P/q where p and q are integers and q=0 The best explanation: Q = p/q where p and q are integers and q = 0 is an incorrect option. In the option, q=0 is GIVEN which is incorrect it should be q ≠ 0. All other options are correct since N set includes all positive integers, W set includes all integers and ZERO and Z set includes zero and all positive and negative integers.
