Im sorry... I don’t think it is -18... let me explain
2/3 is less than 1 and -9/4 is almost -2
And 1 times -2 is -2. So I don’t think it can possibly be -18
So what im saying the answer is:
-3/2
Explanation:
Just multiply like you would any fraction:
2/3•-9/4 = -18/12
And if you simplify that you get -3/2 or -1 and 1/2
Brainliest my answer if this helps?
