Answer:
5 1/3 ounces
Explanation:
1 pint is equal to 16 ounces.
The recipe asks for 1 pint of sour cream (16 ounces).
The chef needs to use only 1/3 as much as the recipe asks for.
Therefore, the amount of sour cream that the chef needs to use is:
1/3 * 16 = 5 1/3 ounces
The chef would use 5 1/3 ounces of sour cream.
