State whether True or False:

If a number is divisible by 10, then it must also be divisible by 5.

Divisibility by 5:

If the ones digit of a number is 0 or 5, then it is divisible by 5.

Divisibility by 10:

 A number is divisible by 10 when its ones digit is 0.

So, every number divisible by 10 must also be divisible by 5.

We also know that the prime factors of 10 are 5 and 2. Therefore, numbers that are divisible by 10 will be divisible by 2 and 5.

Therefore, the given statement is True.
