Let's break it down! If every 5 students who choose the art museum corresponds to 4 students at the science museum, we can set up a ratio of art to science as 5:4. For every 9 students (5+4=9), 5 go to the art museum and 4 go to the science museum. Now, we can determine how many groups of 9 fit into our class of 27: 27 ÷ 9 = 3 groups. So, multiplying each part of the ratio by 3: Students at the art museum: 5 * 3 = 15 Students at the science museum: 4 * 3 = 12 Finally, the difference is 15 - 12 = 3 students. So, 3 more students visit the art museum than the science museum.
