Here is the question: If a natural number is divisible by 5 and 2, then it must also be divisible by 10. My answer: false. Is this correct?

What number are you thinking of that is divisible by 5 and 2 but not by 10? If you have that number, then you know you are correct or not?

If a number is divisible by 2 AND 5, then it must be divisible by 10.
Reason: 2*5 = 10
