Math Problem Statement

solve

Which ratios are equivalent to the one given in the scenario? A school has 1,360 students and 80 teachers.

Solution

To determine the correct answer, we first need to find the student-to-teacher ratio given in the problem.

Step 1: Calculate the Initial Ratio

The school has:

  • 1,360 students
  • 80 teachers

So, the ratio of students to teachers is: 136080=17 students per teacher\frac{1360}{80} = 17 \text{ students per teacher}

Step 2: Identify Equivalent Ratios

Now, let's check each of the provided options to see which match this ratio.

  1. 170 students to 10 teachers
    17010=17\frac{170}{10} = 17 — This matches the original ratio.

  2. 2 students to 34 teachers
    234=11717\frac{2}{34} = \frac{1}{17} \neq 17 — This does not match.

  3. 34 students to 2 teachers
    342=17\frac{34}{2} = 17 — This matches the original ratio.

  4. 10 students to 170 teachers
    10170=11717\frac{10}{170} = \frac{1}{17} \neq 17 — This does not match.

Conclusion

The two ratios that are equivalent to the original are:

  • 170 students to 10 teachers
  • 34 students to 2 teachers
