Students in Class 1, Grade 3 of a certain school bought 150 meters of red ribbons for the Chinese festival. They needed 12 meters of red ribbons to make a big Chinese festival, and 6 meters of red ribbons to make a small Chinese festival. If you make 4 big Chinese festivals, how many small Chinese festivals can you make with the remaining red ribbons?
