Answer:
The answer is -1/6.
Explanation:
First, we must multiply 4/9 and 3/4 which gives us 12/36 which simplifies to 1/3.
Next, we find the common denominators of -1/2 and 1/3 which is 6.
Then, we try and make it to where our denominators are equal, -3/6 + 2/6.
Finally, we add. -3/6 + 2/6 = -1/6
Therefore, our answer is -1/6.
