Final answer:

McKenna starts with 1 2/3 cups of milk and gives away 3/4 cup. After performing fraction subtraction, she is left with 11/12 cups of milk.

Step-by-step explanation:

The question involves McKenna who has 1 2/3 cups of milk and gives Mark 3/4 cup of milk to make a cake. To find out how much milk McKenna will have left, we subtract Mark's portion from McKenna's original amount:

  1. Convert 1 2/3 to an improper fraction, which is 5/3 (since 1 2/3 = 3/3 + 2/3 = 5/3).
  2. Subtract 3/4 cup from 5/3 cups.

5/3 - 3/4 = (5×4)/(3×4) - (3×3)/(4×3) = 20/12 - 9/12 = 11/12

  1. Convert 11/12 back to a mixed number if necessary. Here it's not required since 11/12 is less than 1 and can't be converted into a mixed number.

Therefore, McKenna will have 11/12 cups of milk left after giving some to Mark.
