Answers

The ratio that does not illustrate a comparison from the items created in Suzanne's bakery is option D) 2:4 to signify cakes to pies.

What is ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the twonumbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Suzanne was baking treats for her bakery's grand opening.

Since, She made 4 cakes with 8 cups of flour. She baked 2 pies and 3 dozen cookies.

Option A) 1:9 signifies a comparison of the number of cakes to the number of cookies.

Option B) 1:18 signifies a comparison of the number of pies to the number of cookies.

Option C) 2:1 signifies a comparison of the number of cakes to the number of pies.

However, option D) 2:4 does not illustrate a comparison between any of the items created in Suzanne's bakery.

This is because there are no given ratios for the number of cakes to the number of pies, or the number of cakes to the number of cakes plus pies.

Therefore, option D) is the correct answer.
