The ratio of oranges and bananas is 3:6. There are 54 pieces of fruit altogether, how many of them are oranges?
Do I set it up 3/6 times x/54?

Oh, I've got it! It's 27!:)
No.
27 is half of 54. If half of the fruits are oranges and half are bananas, then the orange-to-banana ratio would be 1:1 (for every 1 orange there is 1 banana). That's not what you want.

yea i don't think its 27 eathier if i knew i would of helped but i don't lol:)
I think you started okay. You probably reduced the ratio 3:6 down to 1:2. But that does NOT mean 1/2.
1/2 means 1 out of every 2.
1:2 means 1 out of ever 3. That is, for every 1 of the first, there are 2 of the second: therefore, there are 3 altogether.
so it should be (1/3)54 = 18 oranges
PS: And (2/3)54 = 36 bananas.
Add them up and you do indeed get 54 fruits. And, if you compare the number of oranges, 16, to the number of bananas, 36, you do get a 1:2 ratio.
