Video Summary

A painter mistakenly mixed 3 liters of blue paint with 2 liters of yellow paint, instead of the desired 2 liters of blue with 3 liters of yellow for 5 liters of green paint. To correct this, he needs to discard 1.666 liters (1666 milliliters) of the mixed paint. By then adding 1666 milliliters of yellow paint to the remainder, he achieves the correct 2:3 ratio of blue to yellow, successfully making the desired green paint. Thus, the smallest amount of paint he must throw away is 1.666 liters.
