Final answer:
Jake should measure 4 pints of milk, as 1 pint equals 2 cups, and he needs 8 cups for his chocolate shake.
Step-by-step explanation:
Jake needs to convert cups to pints to determine how many pints of milk to use for his chocolate shake. Since 1 pint is equal to 2 cups, he can use unit equivalence to do the conversion. To find out how many pints equal 8 cups, we divide the number of cups by the number of cups in a pint:
- Identify the conversion factor, which is 1 pint = 2 cups.
- Since Jake needs 8 cups, divide 8 cups by the number of cups in a pint (2 cups/pint): 8 cups ÷ 2 cups/pint = 4 pints.
Therefore, Jake should measure 4 pints of milk to get the 8 cups needed for his shake.
