If A= {2,4,6,9} and B= {4,6,18, 27, 54}, a in A, b in B , find the set of ordered pairs such that 'a' is a factor of 'b' and a lt b

If A = {a,b,c,d}, B = {1,2,3}, Which of the following sets of ordered pairs are not relations from A to B ?

Express A={(a ,b):a+b=4,a ,b in W} as the set ordered pairs.

If A = {1, 2, 3,9, 4, 5}, B = {1, 4, 5,8,9,6} then find n ( A ∪ B ) .
