2/3 of flour to make 6 muffins what is the unit rate for cups of flour per muffin? for muffins per cup of flour?

Amount of sugar 2 cups, amount of flour 3 cups, this means that for every cup of flour you  will need 2/3 of cup of sugar. if you have only 2 cups of flour you will need (2/3)*2 cups of sugar = 4/3 0r 1 cup and 1/3 more.

Ask google i believe they can you with that question
