I need to set up a proportion for this question:
A recipe for chocolate chip cookies requires a half cup of sugar for a serving of 8 cookies. You need to make 30 cookies for your Math class and decide to use proportions to calculate how much sugar you need.
Tell me if I am doing this right please :)

I know that 1/2cup sugar = 8 cookies so that means that C = 30. I need to find out what C is. I think that maybe I would set up the proportion like this but I'm not sure: dw:1330997293354:dw And then I would cross multiply. The only thing I'm not sure I'm doing right is setting up the proportion. Please let me know. Thank you :)

The best way, not to get confused again is, use a heading Cup : Cookies Now try it

Oh and I am using the C to represent the unknown CUP of sugar. I suppose I could have used S for sugar but oh well :p

Cup : Cookies 0.5 : 8 x : 30 Now cross multiply.
