Vanessa was baking cookies. each batch of cookies made 3 dozen. if vanessa uses 6 cups of flour total and each batch requires 1 1/2 cubs of flour, how many dozen cookies did she make?

Each batch gives you 3 dozen and you need 1 1/2 cups for each batch of cookies

she uses 6 cups in total, so divide 6 by 1 1/2 to get the number of batches

6 ÷ 1 1/2 = 4 batches

so 4 batches × 3 dozen cookies = 12 dozen cookies

Same length is comparing because it’s saying its the same and not different
