Bertie needs 2 1/3 cups of flour fro each pan of biscuits she bakes. she wants to bake 3 1/2 pans. how many cups of flour does bertie need?

You're going to multiply how much she need by how many she wants to make: 2 1/3x3 1/2. First make them improper fractions: 7/3x7/2. Then multiply the numerators together and the denominaters together: 49/6. Simplify: 8 1/6. She needs 8 1/6 cups of flour :)
