Jin is writing a recipe for a cake frosting. His recipe makes 3 cups of white frosting. He'd like to add an optional step to add color to the frosting. Which is the best estimate for how much food coloring should be added in this step, 3 pints ot 3 milliliters?

The best estimate for how much food coloring should be added in this step is 3 milliliters. Pints are a much larger unit of measurement compared to milliliters. Adding 3 pints of food coloring to a recipe that only makes 3 cups of frosting would likely be way too much and overpower the frosting with color. Adding 3 milliliters would give a more appropriate amount of color for the frosting.
