Peter and Jess are both making cookies. For Peter's recipe, he uses 3 cups of sugar to make 78 cookies. Jess uses 5 cups of sugar to make 130 cookies. is the ratio of the flour to the number of cookies the same for both recipes?
(a) yes
(b) no
To determine if the ratio of flour to the number of cookies is the same for both recipes, we need information about the amount of flour used in each recipe. The given information only mentions the amount of sugar used in each recipe. Therefore, we cannot determine if the ratio of flour to the number of cookies is the same for both recipes.
Therefore, the correct answer is (b) no.
