6/2(2+1) = 9 or 6/2(2+1) = 1 I am not really sure which is the correct answer. I think the latter is much more correct than the former. If we assume the property of distribution then the latter can be made into this 6/2(2+1) = 6/(2*2 + 2*1) = 1.

1$\dfrac{6}{2}(2+1)=9$ while $\dfrac{6}{2(2+1)}=1$. Which one do you mean? – Henry Jun 27 '18 at 07:50

Both are correct. The "standard" order of operations is ambiguous when it comes to division and multiplication, and this confusion is best avioded by using parentheses or fractions, writing either $$ \frac62(2+1)\quad\text{or}\quad\frac6{2(2+1)} $$ or $$ (6/2)(2+1)\quad\text{or}\quad6/(2(2+1)) $$

Following the order of operations we get, $$ 6/2(2+1) = (6/2)(3)=3(3)=9 $$
We better avoid confusion by adding another parenthesis.
$$ (6/2)(2+1) =9$$.
