Answer 2

SOLUTION

TO FILL IN THE BLANK

If every element of A is also an element of B, then A is called ______ of B.

EVALUATION

We know that set is a well defined collection of distinct objects of our perception or of our thought to be conceived as a whole

Now a set A is said to be a subset of B if every element of A is an element of B . It is written as A ⊆ B

For example :

A = { 1 , 2 } , B = { 1 , 2 , 3 , 4 }

Then every element of A is an element of B .

So A ⊆ B

FINAL ANSWER

If every element of A is also an element of B, then A is called subset of B.
