Question 925524: Could you please help me setup the problem below. I get confused on when what to use as the numerator and denominator
A pancake batter consists of 4 cups of mix and 3¾ cups of water. How much water is needed if you use 6 cups of mix?
My approach is below. Did I setup this problem correctly?
mix/water = 4/(3 3/4)=6/x

Your proportion equation is correct.
----
To be sure about where to put the numbers I suggest
you 1st write the proportion in words, such as
mix/water = mix/water or water/mix = water/mix
---
Then substitute the proper numbers into the equation.
Then solve for the missing quantity.

3 3/4 = 15/4
---
4 mix / (15/4 water) = 6 mix / x water
4/(15/4) = 6/x
x = (15/4)*6/4
---
answer:
x = 5.625 cups of water

4%2F%283%263%2F4%29+=+6%2Fx
Yes you did!! Good job!!
You just need to cross-multiply now, as follows:
4x+=+6+%2A+3%263%2F4
