b. kates class
c. neither. the class have the same ratio

Answer 1

To determine which class has a greater ratio of students who wear glasses to the total number of students, we can calculate the ratio for each class.

**Janet's Class:**
- Number of students who wear glasses: 15
- Total number of students: 25

Ratio for Janet's class:
\[
\frac{15}{25} = \frac{3}{5} = 0.6
\]

**Kate's Class:**
- Number of students who wear glasses: 12
- Total number of students: 20

Ratio for Kate's class:
\[
\frac{12}{20} = \frac{3}{5} = 0.6
\]

Both classes have the same ratio of 0.6.

Therefore, the answer is (c) neither. The classes have the same ratio.
