Because every alternate multiple is also divisible by ten - therefore it ends in zero !
Every other number that ends in 5 is a multiple of 5 this is why
Any multiple of 10.
A multiple of 10 must end in a zero
If a number is a multiple of 5, it will be greater than 5 and end in a 5 or a zero.
Every whole number that ends with ' 5 ' or ' 0 ' is a multiple of 5 . Every whole number that ends with ' 0 ' is a multiple of 10.
Not all (5 is prime) but every multiple of 5 greater than 5 is composite because they have more than two factors. Every multiple of any integer greater than one is composite.
yes because if it has a zero or five at the end you know its a multiple of 5
10, 20, 30.... Any even multiple of five.
Yes.
Every whole number that ends in 5 is a multiple of 5 .It doesn't matter what comes before the 5 .
No. Every other multiple of 5 is even. The odd multiples of 5 end in 5, such as 5, 15, 25, 35, etc., making them odd, and the even multiples of 5 end in 0, such as 10, 20, 30, etc, making them even.
It doesnt.
