Answer: 2 : 1
Explanation:
The batter calls for 2 cups of flour and 1 cup of milk.
That means that for every 2 cups of flour, the muffin batter would need 1 cup of milk.
Ratio of flour to milk will therefore be:
= Amount of flour needed : Amount of milk needed
= 2 cups of flour : 1 cup of milk
= 2 : 1
