Question

If B = {−13, −9, −7, −3}, choose the set A that will make the following statement false.

B ⊆ A
a. A is the set of negative odd integers
b.A is the set of integers
c.A is the set of rational numbers
d.A is the set of whole numbers

Answer 1

Answer: c.A is the set of rational numbers

Explanation:

B ⊆ A means that every element of B is an element of A

B = { -13 , -9 , -7 , - 3 }

The element of B are negative integers , this mean that the element of A must also be integers therefore :

Option a is correct.

Option b is also correct

Rational numbers are numbers that can be express in the form a/b , examples are : 1/2 , 3/ 4 , 5/6 ...

clearly , this does not necessarily define A , so option c is the odd one out
