If is a homomorphism, then we have, for every
Since G is abelian, we have , and thus
But we also have
which proves that G' is abelian.
In other words, for every , you have , because there exist such that , and you can think of as , and of and
Then, you observe that because they mean , and by hypothesis, because G is abelian.

2 scarves
That is the information we know. What we want to do is find out how many scarves for 14 skeins of yarn, like this
4 14
-- = ---
2 ?
To get from 4 to 14, you multiply by 3.5. We must to the same thing to the bottom as well. So we multiply 2 by 3.5, which gives us 7
x3.5
4 14
-- = ---
2 7
x3.5
