At Crescent High School, 108 students plan on going to an in-state college and 63 students plan on going to an out-of-state coll
ege. What is the ratio of students planning on going to an in-state college to students planning on going to an out-of-state college? A.
12:7
B.
108:1
C.
7:12
D.
1:108
The ratio we want to find can be thought of in the form in:out
We list the number of "in-state" people first followed by the "out-of-state" people next. A colon separates the two values. So we have the initial ratio of 108:63
Divide both parts by the GCF 9
108/9 = 12
63/9 = 7
The ratio 108:63 fully reduces to 12:7 meaning there are 12 in-state students for every 7 out-of-state students. The order is important because 7:12 would be incorrect and imply we had 7 in-state vs 12 out-of-state.
