How did he get his answer 0.51???
It is a typo, the choice should be 0.26.
another question, why is 15 a prime number? isn't it divisible by 3? and the definition for prime number is "Divisible by ONLY itself AND 1"
15 isn't prime, as it is divisible by 3 and 5.
lol i guess another typo... thanks
If that were the definition of prime number, would that not mean that 1 is a prime number?Quote:

Topic: Multiple
Definition: Number multiplied by an integer
Example: The first multiple of 6 is 6, then 12
"A is a multiple of B", where A and B are integers, means that there exist some integer C such that A= BC.
6 is a multiple of 6 because it is equal to 1(6). That is, C= 1. 12 is multiple of 6 because 12= (6)(2). It is the "1" and "2" that causes them to say "first" multiple and "then". The next few multiples are 3(6)= 18, 4(6)= 24, 5(6)= 30, etc.
so can we say that 12 is a multiple of 2??
and can we also way that 12 is a multiple of 12 because it is equal to 1(12). That is, c= 1?
never mind i get it lol thanks
