Ellie bought 6 liters of fruit punch for a party. She will serve the punch in glasses that can hold 300 milliliters. How many full glasses of fruit punch can she serve?

There are 1000 milliliters in 1 liter, so Ellie has 6 x 1000 = 6000 milliliters of fruit punch.

To find the number of glasses she can serve, we need to divide the total amount of punch by the capacity of each glass: 6000 / 300 = 20.
Therefore, Ellie can serve 20 glasses of fruit punch.
