You can put this solution on YOUR website! Answer each of the following and justify your answers.
a. If a number is not divisible by 5, can it be divisible by 10?
No.
If it's not divisible by 5, it has no factor of 5. 10 has a factor of 5.
--> not divisible by 10
------------------
b. If a number is not divisible by 10, can it be divisible
by 5?
Yes.
An example is sufficient:
35 is not divisible by 10, but is by 5.
This applies to 5 x any odd integer.
