Answer:
Helena uses double the amount of water to the amount of vinegar.
Step-by-step explanation:
- A unit rate is a ratio that is used to compare different kinds of quantities.
A unit rate describes how many units of the first quantity corresponds to one unit of the second quantity.
So, unit rate of water to vinegar means how much water is needed corresponding to 1 unit of vinegar.- Formula:
\(\text{Unit Rtae} = \displaystyle\frac{\text{Amount of Water}}{\text{Amount of Vinegar}} = \displaystyle\frac{5}{2\frac{1}{2}} = 2\)
- Thus, for every 1 unit of vinegar, one needs two units of water.
Thus, Helena uses double the amount of water to the amount of vinegar.
