How do i find the missing number in a proportion?
24/12 = 8/x

Math 
Ms. Sue,
You cross multiply and solve for x.
24x = 8 * 12
24x = 96
x = ?? 
Math 
Bryan,
Cross multiply then divide. I figured it out. the answer would be 32
24/12 = 8/32 
Math 
stuckinmath,
24x = 8 * 12
24x = 96
96/24=4
So X=4 
Math 
DrBob222,
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 
Math 
Bryan,
That's what i got. I got x = 4. Why you say No?

Math 
Ms. Sue,
DrBob was responding to your answer. It is not 32.

Math 
DrBob222,
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.
