A baker used 12 cups of batter to make muffins. It took 2/3 cup of batter to make 1 muffin. How many muffins did the baker make? (A) 6 muffins (B) 8 muffins (C) 18 muffins (D) 36 muffins

Answer:   (C) 18 muffinsStep-by-step explanation:(12 cups)/(2/3 cups/muffin) = 12·3/2 muffins = 18 muffins_____You can consider this as a unit conversion problem. You have units of cups, and you want units of muffins. Then you need to multiply by a number that has units of muffins/cup. You have a number that has units of cups/muffin (the inverse of the desired conversion factor), so you can do the required conversion by dividing by that number.
