Question

in school it is told that for question number 6 which set of
numbers will be the universal set for the set given below? A= to
set of multiple of 5 Set B= to multiples of 7 and Set C= to
multiples of 12 so can we write answer as real number, instead of
natural numbers, integers, rational number, and whole number??

Dear student,

Since 5,7 and 12 are coprime to each other, hence the HCF of 5,7
and 12 is 1 and hence thereis nothing common between multiples of
5,7 and 12 So the universal set for all the sets A,B and C can be
the set of all real numbers because it includes A,B and C

So you can definiitely write it as your answer
