Answer:
David 1,988-1,956+32
It is David because when you find the unite ratio you get 1,988 for David and 1,956 for Megan.
Answer:
- Anna: 2/5 cup
- Bailey: 3/8 cup
Step-by-step explanation:
Anna's recipe makes 2+3 = 5 cups of lemonade, of which 2 cups are concentrate. Thus, concentrate makes up 2/5 of the volume of Anna's lemonade. 1 cup of it will contain 2/5 cup of concentrate.
Bailey's recipe makes 3+5 = 8 cups of lemonade, of which 3 cups are concentrate. Thus, concentrate makes up 3/8 of the volume of Bailey's lemonade. 1 cup of it will contain 3/8 cup of concentrate.

I know this because I did the math. The assumption is that the concentrate is well-mixed in each case.
No. For fractions to be equal, both the numerators and denominators have to be proportional.
Since both denominators are 2, the denominators would have to be just 3 or just 4.
The median will change; the mode will stay the same.
<h3>Will the median and mode change?</h3>
The median is the number that is at the center of a data set when the data are arranged either in ascending or descending order.
Median = 23
When 68 and 75 are added, the median would change.
Mode refers to a value that appears most frequently in a data set.
The mode = 75
So, when 75 is added, the mode does not change.
