Answer:
Therefore, Zach would use 1/15 of a cup of vinegar to make 1/6 of the recipe.
Explanation:
To find out how much vinegar Zach would use to make 1/6 of a recipe, we can set up a proportion using the given information.
We know that Zach uses 2/5 of a cup of vinegar for the full recipe. Let's represent the amount of vinegar Zach would use for 1/6 of a recipe as "x."
The proportion can be set up as:
(2/5) / 1 = x / (1/6)
To solve for x, we can cross-multiply and then divide:
(2/5) * (1/6) = x * 1
2/30 = x
Simplifying the fraction, we have:
1/15 = x
