You cross multiply and solve for x.

24x = 8 * 12

24x = 96

x = ??

Cross multiply then divide. I figured it out. the answer would be 32

24/12 = 8/32

24x = 8 * 12

24x = 96

96/24=4

So X=4

No, 24*x = 8*12

24x = 96

x = 96/24 = 4

Another way of looking at it is

24/12 = 8/x

2 = 8/x

2x = 8

x = 4

That's what i got. I got x = 4. Why you say No?

DrBob was responding to your answer. It is not 32.

Go back and look at your post.

You wrote, "Cross multiply then divide. I figured it out. the answer would be 32

24/12 = 8/32

**So, I said No. The answer is x = 4 and not 32.**
