Question

Of the students in Oscar's grade, 1 student has a pet and the other 48 students do not. What is the ratio of the number of students who have a pet to the total number of students?
2:1 1:49 48:49 48:1

Answer 1

To find the ratio of the number of students who have a pet to the total number of students, we first need to determine the total number of students.

Oscar's grade has:
- 1 student who has a pet
- 48 students who do not have a pet

So, the total number of students is:
\[ 1 + 48 = 49 \]

Now, we can express the ratio of the number of students who have a pet (1) to the total number of students (49):

\[
\text{Ratio} = \frac{\text{Number of students with a pet}}{\text{Total number of students}} = \frac{1}{49}
\]

This ratio can be expressed as:
1:49

Thus, the answer is:
**1:49**
