Answer:
1/2 cup of milk
Explanation:
Given
Total cup of milk needed = 3/4 cup of milk
Amount she has = 1/4 cup of milk
The amount of milk she needed = Total - Amount she has
Amount she needed = 3/4 - 1/4
Amount she needed = (3-1)/4
Amount she needed = 2/4
Amount she needed = 1/2
Hence she needs 1/2 cup of milk more
