Question

A recipe calls for 15 oz of flour for every 8 oz of milk .is the relationship between ounces of four and ounces of milk proportional explain

Answer 1

Yes, there is a proportional relation.

Explanation:

Given,

Ounces of flour for 8 ounces of milk = 15,

So, the ounces for 1 ounces of milk =
`(15)/(8)`

Let y be the ounces of flour for x ounces of milk,

∵ The ounces for x ounces of milk =
`(15)/(8)x`

`\implies y = (15)/(8)x-----(1)`

Which is the required relation,

Since,

`0=(15)/(8)(0)` ( True )

I.e. line
`y=(15)/(8)x` passes through the origin,

Hence, the relationship (1) is proportional.

Answer 2

Yes, they are proportional because if you increase or decrease either amount they will both change. They will always have the same size. For example if I want to double the flour, I will have to double the milk as well because they have the same ratio.
