Question

jenny makes plaster using a ratio of 4 cups of water to 5 pounds of plaster powder. whose plaster recipe uses more water? use the ratio table here and in exercise 4 to compare.

Explanation:

Step1: Find the multiplier for the first - row value change

The first - row value of water changes from 4 to 8. The multiplier is $\frac{8}{4}=2$.

Step2: Apply the multiplier to the powder amount

Since the ratio of water to powder is 4:5, when the water amount is multiplied by 2, the powder amount is also multiplied by 2. So for 8 cups of water, the powder amount is $5\times2 = 10$ pounds.

Step3: Generate more ratio values

If we multiply the original ratio 4:5 by 3, we get 12 cups of water and $5\times3=15$ pounds of powder. If we multiply by 4, we get 16 cups of water and $5\times4 = 20$ pounds of powder.
The completed table is:

Cups of Water	4	8	12	16

However, since the problem doesn't provide another recipe for comparison, we assume we just need to complete the table.

Answer:

Cups of Water	4	8	12	16
