Step-by-step explanation:

Bertie needs 2 1/3 cups of flour for each pan of biscuits she bakes. She wants to bake 3 1/2 pans of biscuits. How many cups of flour does Bertie need?

Answers

Bertie needs 12 1/4 cups of flour to make 3 1/2 pans of biscuits.

What is multiplication?

The basic idea of multiplication is repeated addition. But as well as multiplying by whole numbers, we can also multiply by fractions, decimals and more.

Given that, Bertie needs 2 1/3 cups of flour for each pan of biscuits she bakes. She wants to bake 3 1/2 pans of biscuits.

Since, 1 pan needs 2 1/3 cup of flour.

So, for 3 1/2 pans = 3 1/2 × 2 1/3

= 7/2 × 7/2

= 49/4

= 12 1/4

Hence Bertie needs 12 1/4 cups of flour to make 3 1/2 pans of biscuits.

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 :)
