Answer:
"No, the relationship is NOT proportional"
Step-by-step explanation:
<u>Complete Question:</u>
Of the 75 boys in the 7th grade class, 25 participate in at least one sport. Of the 120 girls in 7th grade class 30 participate in at least one sport. Is this relationship proportional?
We have to see the ratio of each and if they are equal (after reducing), we can say they are proportional.
Boys:
25 participate in atleast 1 sport and there are total of 75. Hence, ratio is
25 : 75 = 1 : 3
Girls:
30 particiapte in atleast 1 sport and there are toal of 120. hence ratio is:
30 : 120 = 1 : 4
So, the relationship is NOT proportional
The correct answer should be D
