Answer :
A) The double Number Line graph that shows the ratio relationship between the number of tablespoons of milk and the number of cups of tea in Adesh's recipe is
Tea: 0 3 6 9 12
Milk: 0 4 8 12 16
B) The double Number Line graph that shows the ratio relationship between the number of tablespoons of milk and the number of cups of tea in Kelly's recipe is
Tea: 0 5 10 15 20
Milk: 0 7 14 21 28
C) Adesh uses slightly less milk per cup of tea compared to Kelly.
Part A: Ratio Relationship in Adesh's Recipe
Adesh's recipe uses 4 tablespoons of milk for every 3 cups of tea. The ratio of milk to tea is 3/4
Table:
Cups of Tea | Tablespoons of Milk
------------------|---------------------
3 4
6 8
9 12
12 16
Part B: Ratio Relationship in Kelly's Recipe
Kelly's recipe uses 7 tablespoons of milk for every 5 cups of tea. The ratio of milk to tea is 7/5
Table:
Cups of Tea | Tablespoons of Milk
------------------|----------------------------
5 7
10 14
15 21
20 28
Part C: Comparing the Ratio Relationships
Adesh's Ratio: 4/3 = 1.33
Kelly's Ratio 7/5 = 1.4
The ratios are different, meaning Adesh's and Kelly's recipes do not use the same ratio relationship between the number of tablespoons of milk and the number of cups of tea.
