Question

Let n be an integer in the conditional statement below.
If the last digit of n is zero, then n is divisible by five.

The hypothesis is:

The conclusion is:

The converse is:

The contrapositive is:

Answer 1

Hypothesis: The last digit of n is 0.

Conclusion: n is divisible by 5.

Converse: If n is divisible by 5, then the last digit of n is 0.

Contrapositive: If n is not divisible by 5, then the last digit of n is not 0.

(For example, the converse is false: 15 is divisible by 5 but its last digit is 5, not 0.)
