Acatering company’s recipe for salad uses a ratio of 2 c of dressing to 4 lb of vegetables. (hint: c = cups; lb = pounds) (a) how many cups of dressing will be needed if 30 pounds of vegetables are used? (b) draw a model for the ratio. the butterfly method works well for this.

A. 15 cups

B. Diagram below

We are given that,

The ratio of dressing to the vegetables is 2 cups : 4 pounds.

A. It is given that the vegetables are of 30 pounds.

Let the number of cups be x.

Since, the ratio of dressings and vegetables will remain same.

We have,

i.e.

i.e. x= 15

Thus, we will need 15 cups of dressings for 30 pounds of vegetables.

B. As we have obtained the fractions,

2 cups : 4 pounds and 15 cups : 30 pounds

Using the butterfly method, we see from the diagram that these fractions are equivalent because the product of the numbers is equal to 60.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
