This is probably going to sound like a very stupid question but I'm more of a designer than a maths person unfortunately.

I'm just trying to work out how I'd get a new weight of an ingredient for a serving size when I know that current weight for a serving.

So I have 3000mg of Ingredient "A" in a 5.1gram serving. I need to work out how much I have in an 8gram serving.

I thought it was just a case of (3000 / x) \* 8 = value But obviously the more I increase x the less the value is.

As i said probably a really easy question but I'm struggling :)
