Question
Determine if each biconditional is true. If false, give a counter example.A number is a multiple of 20 if and only if the number ends in a $0 .$
Step 1
The statement is "A number is a multiple of 20 if and only if the number ends in a 0." This means that if a number is a multiple of 20, then it must end in a 0, and if a number ends in a 0, then it must be a multiple of 20. Show more…
