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.

Can anyone explain this better to me???? I don't exactly grasp this concept...

Topic: Multiple

Definition: Number multiplied by an integer

Example: The first multiple of 6 is 6, then 12 - Nov 30th 2012, 01:47 PMHallsofIvyRe: Fundamental Math
"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. - Nov 30th 2012, 05:15 PMasilvester635Re: Fundamental Math
so can we say that 12 is a multiple of 2??

- Nov 30th 2012, 05:16 PMasilvester635Re: Fundamental Math
and can we also way that 12 is a multiple of 12 because it is equal to 1(12). That is, c= 1?
