Respuesta :

One batch of muffins needs 2/3 of a cup.

12 * 2/3 = 8 cups. He needs 8 cups of milk for 12 batches of muffins. So he has enough milk.

To make a batch of muffins David needs 2/3 cup of milk

To find if he has enough we can model

(2/3)x = 12

get x by itself

x = 8 cups are needed

David has enough.
