The ochestra at stripling middle school is responsible for cleaning a 15 mile highway. there are 45 students in the orchestra. If each member cleans and equal section, what decimal represents this section?
A.0.3
B.0.33
C.o.3333...
D.3.0
15 mi/45 students = 0.333333. You have two significant figures both in 15 mi and in 45 students; therefore, the answer should be rounded to 0.33 (to two s.f.).

To find the decimal that represents the section of highway each student cleans, we divide the total length of the highway (15 miles) by the number of students in the orchestra (45).
So, the decimal representing the section of highway each student cleans is:
15 miles ÷ 45 students = 0.3333...
Therefore, the answer is option C, 0.3333...
