Question

Test the conditional statement and its converse to determine whether the following biconditional is true.

A number is divisible by 10 if and only if it is divisible by 5.

It is false because both parts of the biconditional are false.

It is false because at least one part of the biconditional is false.

It is true because at least one part of the biconditional is true.

It is true because both parts of the biconditional are true.

Answer 2

split the biconditional into the conditional statement + its converse

conditional statement --> if a # is divisible by 10 then it is divisible by 5
converse --> if a # is divisible by 5 then it is divisible by 10

see if both of these are true or not
