Yes and if you want it to be 1/3, then you should write (1/3). Otherwise A is taken to mean the number directly before the brackets.

Simply doesn't matter.
A = 6/2, B = 1, C =2
A (B + C) = AB + BC
6 / 2 (1 + 2) = 9
(1 + 2) is NOT a denominator PERIOD. If it were it would be 6 / (2 (1 + 2)) but it is NOT.

No kidding, but I didn't write that did I?
1/3(B + C) = B/3 + C/3 or 1/3B + 1/3C
A ( B + C) = AB + BC

Guys, what is 15y ÷ 5y ?
Did you get 3 or 3y^2 ?
If your answer was 9 in previous question, you should get 3y^2 because
15y ÷ 5y = 15 x y ÷ 5 x y
= 15y ÷ 5 x y
= 3y x y
= 3y^2
What if you got answer 1 for previous question?
15y ÷ 5y = 15y/5y
= 3
So, back to the question 6÷2(1+2)=?
Let x = (1+2) = 3 -------------eq 1
6÷2x = 3/x
Put eq 1 into 3/x, you get
3/3 = 1

Exactly! Much the same as
6÷2(1+2) != 6÷2*(1+2).

15y ÷ 5y
The way you have it written it seems obvious that you want it interpreted as:
15*y
------
5*y
However if you follow the rules of a linear equation such as the one you have written, technically you would need parentheses to denote what is in the denominator.
15 x y ÷5 x y Interpreted linearly is technically
15*y
-------- * y
5
which would be 3yy or 3(y^2)
It is obvious what you are attempting to write, but technically parentheses are required to put the 5y in the denominator.

15y is 3 times bigger than 5y!!

Answer would be 3y and that is not a solvable equation. Only one taht can be simplified.

Simplified it is just 3y. Not 3yy or anything else.... just 3y. It is also a problem that cannot be solved just simplified.
