Question

Can someone please help me understand why the coefficient of 'a' in a over 2 is 1/2 instead of 1?

Answer 1

Explanation:

a/2 (a over 2) is rewritten as a×1/2 (a multiplied by half ) so now you can easily see that the coefficient of "a" is 1/2

Answer 2

What you need to consider is what multiplied by 2 results in a/2. This number is the coefficient of a.

We can easily see that a/2 = 1/2 * a and therefore the coefficient is 1/2.
