Answer:0.666666666666 or 2/3
Explanation:
What you are doing here is actually pretty simple, since you have a variable (t) and you have its value (8/9) all that you have to do is place the value where your variables is in the equation. 8/9 x 3/4 = 0.666666666666 or 2/3! what you would do to get the final answer is multiply across, so, 3x8 =24 and 4x9 = 36, so far you're at 24/36 which you'd need to simplify to get 2/3!
