Joanna needs 4 cups of milk to make pudding. She had 3/4 cup of milk at home. She goes to borrow milk from her neighbors. One neighbor has 3/4 cup, and two other neighbors give her 1/2 cup. How much more milk will she need.

The answer to your question is 3/2 cups

Step-by-step explanation:

Data

Milk needed = 4 cups

Milk that she has = 3/4

Milk her neighbor has = 3/4

Milk the second and third neighbors have = 1/2

Process

1.- Calculate the Milk that Joanna has

        3/4 + 3/4 + 1/2 + 1/2 = (3 + 3 + 2 + 2) / 4

                                          = 10/4

                                          = 5/2

2.- Subtract the Milk that she has from the Milk needed.

          4 - 5/2 = (8 - 5) / 2

                      = 3/2

3.- Conclusion

Joanna needs 3/2 cups to make a pudding.
