first, gather your important information:
10,033 people total
5,200 people on the home side
rest are visitors
the next step is to figure out your number of visitors. you can find this by: 10,033 - 5,200 = 4,833
so these 4,833 visitors are sitting in 9-equal sized sections. to figure out around how many people sat in each section, you need to divide 4,833 by 9:
4,833/9 = 537
about 537 visitors sat in each section.
