Question

A number divisible by 5 is always divisible by 10 true or false ​

Answer 1

The statement 'a number divisible by 5 is always divisible by 10' is false (F).

Explanation:

Let us give an example to prove that the given statement is incorrect.

Let a number be 5. This is divisible by 5. But 5 is not divisible by 10.

The correct statement should be 'a number divisible by 10 is always divisible by 5'.

This happens because 10 has a factor 5.

Let us give an example to prove that our statement is correct.

Let 20 be a number. 20 is divisible by 10, since 20 ÷ 10 = 2. Also, 20 is divisible by 5, since 20 ÷ 5 = 4.
