Answer 1

Info given and question

For this case we know that for each two packages of walnut we have three batches of cookies

She decided to write out the recipe for one batch of cookies. If each packages says that it contains 2 1/4 cups of walnut how many cups of Walnut are in each recipe?

Solution

From the info given we have the following proportional rule:

`\frac{2\text{packages}}{3batches}`

We know that each package containes 2 1/4 cups of Wainut

`2(1)/(4)=(9)/(4)(cups)/(package)`

So we can do the following operation to solve the question:

`\text{cups}=(9)/(4)\frac{\text{cups}}{\text{package}}\cdot(2package)/(3batches)=(3)/(2)(cups)/(batches)`

so then we can conclude that we need 3/2 of cups per each batch
