Kureshi also does a survey of college students to see how many of them have a part-time job. His results are NOT proportional to Miguel's. Which could represent Kureshi's Data?

D) 1300 out of 1950 students surveyed have a part time job

Answer 1

1. yes
2. Reduce or simplify this fraction: 500/750

Answer 2

10(0.075)=.75
10(0.08)=.8
then subtract
0.8-0.75=0.05

B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11

B represents Kureshi's info because it is not proportional to the data of Miguel.
