In a certain school, the ratio of students to teachers is about 12.5 to 1. Approximately how many teachers would there be if the school had an enrollment of 197 students?

16

Explanation

Set up a proportion and solve for the missing term.

\(\frac{students}{teachers} = \frac{125}{1}=\frac{197}{x}\)
1x = 15.76
x = 15.76
You cannot have 15.76 teachers, so round the answer to the nearest whole number, 16.
