1)Use a set model to find how many students prefer multiple choice questions?
- You already know, you said 1/3 prefer it.

2) What fraction of the students prefer either fill-in-the-blank questions or essay questions?
- Find the LCD (lowest common denominator) of all the fractions. I believe it is 30. Multiply both the numerator and the denominator of the fraction by the number that makes the bottom of the faction equal to 30. Then just add the numerator of the fractions that correspond to the students that prefer fill-in-the-blank questions and essay questions.
you should get 5/30 + 3/30 = 8/30
8/30= 4/15


3) What fraction of students don't prefer the true/false questions?
- Use the same fractions you made from the previous problem. Add all the fractions except the true/false questions.
5/30 + 3/30 +10/30 = 18/30
18/30 = 3/5

1) y = 1/3 x, where y is the number of students preferring multiple choice, and x is the total number of students

2) 1/6 + 1/10 = 5/30 + 3/30 = 8/30 = 4/15 of the studentsstudents

3) 1 - 2/5 = 5/5 - 2/5 = 3/5 of the students

1) I think it's 1/3 of however many students there are, but I'm not sure how many there are, so I can't help
2) 1/6+1/10=5/30+3/30=8/30=4/15
3) If everyone but 2/5 don't prefer true/false, then that would be 5/5-2/5=3/5
