22 of the 30 students in Evan's grade have a pet. What is the ratio of the number of students who do not have a pet to the number of students who have a pet?

8 to 22

Step-by-step explanation:

if there are 22 people that have a pet whens there is 30 students in total, you have to do, 30-22, and 30-22=8 meaning there are 8 students who don't have pets.

And if already says 22 students have pets, therefore the answer is

8 to 22

8:22
