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?

Question

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
