Is this relationship between cups of milk and cups of cereal be described by a constant ratio?

Part 4) Yes, the relationship between cups of milk and cups of cereal can be described by a constant ratio, and this ratio is equal to 1/3

Part 5) Yes, the relationship between cups of cereal and servings of cereal can be described by a constant ratio, and this ratio is equal to 3/4

Step-by-step explanation:

Part 4) Can the relationship between cups of milk and cups of cereal be described by a constant ratio?

Let

x ------> cups of milk

y -----> cups of cereal

observing the table

For x=4, y=12

so

For x=6, y=18

so

The relationship between cups of milk and cups of cereal is proportional

therefore

Yes, can be described by a constant ratio, and this ratio is equal to 1/3

Part 5) Can the relationship between cups of cereal and servings of cereal be described by a constant ratio?

Let

x ------> cups of cereal

y -----> servings of cereal

observing the table

For x=12, y=16

so

For x=18, y=24

so

The relationship between cups of cereal and servings of cereal is proportional

therefore

Yes, can be described by a constant ratio, and this ratio is equal to 3/4
