give an example of two ingredients in a recipe that would meet this requirement.
Are you sure you typed that correctly?
I'm very confused on what this is asking. Rates and recipes? I have no idea what this means, and it looks lke nonsense to me, but perhap Melody, CPhil, or geno3141 could help.
I don't think ingredients naturally have rates associated with them. Rates of what?
Also, two ingredients is kind of general.
There are various recipes that use a ratio of one item to another as the rate of 2 : 3.
For instance, for chicken casserole, a recipe may tell you to use 2 cups of cooked rice to 3 cups of cooked (diced) chicken.
Ah, that's what it means. I usually think of that in terms of "ratio" for non-speed based situations. I thought rate was only used for speed. This looks like a poorly worded problem to me.
The wording of the question is very poor mathematician - it would have confused me too :)
The Rate would change. The new recipe is 6 cups of cooked rice for 9 cups of diced chicken.
I think this is such a coincidance because I was looking up this problem for my math class. Did you get the problem in a 7 grades mathbook? That's where I got mine. I am a seventh grader. :)
