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:
[tex]\text{Unit Rtae} = \displaystyle\frac{\text{Amount of Water}}{\text{Amount of Vinegar}} = \displaystyle\frac{5}{2\frac{1}{2}} = 2[/tex]
- 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.
