Answer:

-1/6

Explanation:

Using the PEMDAS rule, we start with the equation in the parentheses (3/4 x 4/9). 3 X 4 is 12 and 4 X 9 is 36, so the answer is 12/36. You can simplify this to 1/3. -1/2 plus 1/3 can also be written as 1/3 - 1/2. Next you will want to set the denominators equal to each other. In this case, I'll set them both equal to 6.

3 x 2 is 6, and 1 x 2 is 2, turning 1/3 into 2/6.

2 x 3 is 6 and 1 x 3 is 3, turning 1/2 to 3/6.

2/6 - 3/6 equals -1/6
