Representing a mixture of seeds in a table.

A recipe for trail mix says: “Mix 7 ounces of almonds with 5 ounces of raisins.” Here is a table to show how many ounces of almonds and raisins would be in different-sized batches of this trail mix.

(1). Complete the table so that ratios represented by each row are equivalent. What methods did you use to fill in the table?

(2). How do you know that each row of the table shows a ratio that is equivalent to 7 : 5 ? Explain your reasoning.
