A collector has 120 movie posters and 80 band posters. She wants to sell 24 movie posters but still have her poster collection maintain the same ratio of 120:80. If she sells 24 movie posters, how many band posters should she sell? Complete the explanation to find out how many band posters she should sell. (I need help with finding the band posters. I'm stuck on 120/80 = 96/____)
