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