You can use place value because that will tell you what place it is in and will make it much more easier
Simply set up a proportion. 1/3 = x/48. Cross multiply afterwards. 48 = 3x. Solve the equation. x = 16. By using proportions which is another form of a ratio you can easily find out that there are 16 adults at the school. Hope this helps :))
