Yes - any number ending in 5 or 0 is a multiple of 5.
A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.
