Question 940648
{{{18/9((12-2)+4)}}}
We will divide the equation by parenthesis starting with the innermost.
That is the (12-2) in the denominator. (12-2)=10 so we can replace (12-2) with 10 
and get rid of the parenthesis.  That gives us:
{{{18/9(10+4)}}}
Next we deal with the remaining parenthesis, (10+4)=14 so:
{{{18/(9*14)}}}
To reduce this, we can write {{{(9*2)/(9*14)}}}. The{{{9/9}}}is one so the final
fraction is {{{2/14}}} or {{{1/7}}}.
