What multiple of 9 and is also a factor of 9?
Oh, dude, that's an easy one! So, a multiple of 9 is any number you get when you multiply 9 by another number, like 18 or 27. And a factor of 9 is a number that divides evenly into 9, which is basically just 1, 3, and 9. So, the only number that fits both categories is 9 itself. Like, it's a multiple of 9 because 9 times 1 is 9, and it's a factor of 9 because, well, it's 9!
