18%2F9%28%2812-2%29%2B4%29
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%2F9%2810%2B4%29
Next we deal with the remaining parenthesis, (10+4)=14 so:
18%2F%289%2A14%29
To reduce this, we can write %289%2A2%29%2F%289%2A14%29. The9%2F9is one so the final
fraction is 2%2F14 or 1%2F7.
