Answer:

See below

Step-by-step explanation:

Ball pen users in first college: 400 students out of 600 = 400/600= 2/3= 66%

Ball pen users in second college: 450 students out of 900 = 450/900= 1/2= 50%

In first college majority of students and in second college half of the students use ball pens.
