Answer:
<u>1. 45/482 of the students are in grade 4.</u>
<u>2. 5/9 of the students of the grade 4 are boys.</u>
<u>3. 7/15 of the grade 4 students are in Ms. Ashley's class</u>
<u>4. 3/4 of the students in Mr. Ben's class do not have siblings in the same school.</u>
<u>5. There are 14 students with glasses and 7 without glasses.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the questions:
Number of students in the school = 482
Ms. Ashley's Grade 4 class = 21 students
Ms. Ashley's Grade 4 class boys = 15 students
Ms. Ashley's Grade 4 class girls = 6 students
Ms. Ashley's Grade 4 class with glasses = 2/3 * 21 = 42/3 = 14 students
Mr. Ben's Grade 4 class = 24 students
Mr. Ben's Grade 4 class boys = 10 students
Mr. Ben's Grade 4 class girls = 14 students
Mr. Ben's Grade 4 class with siblings in the school = 1/4 * 24 = 24/4 = 6 students
2. Let's answer all the questions:
1. What fraction of the students in the school are in grade 4?
(Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)/ Number of students in the school
21 + 24 / 482 =<u> 45/482</u>
2. What fraction of the grade 4 students are boys?
(Ms. Ashley's Grade 4 boys + Mr. Ben's Grade 4 boys)/ (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)
15 + 10 / 21 + 24
25 / 45 = <u>5/9</u>
3. What fraction of the grade 4 students are in Ms. Ashley's class?
Ms. Ashley's Grade 4 class / (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)
21 / 21 + 24
21 / 45 = <u>7/15</u>
<u>4. What fraction of the students in Mr. Ben's class that do not have siblings in the same school?</u>
(Mr. Ben's Grade 4 class - Mr. Ben's Grade 4 class with siblings in the school)/ Mr. Ben's Grade 4 class
24 - 6 / 24
18 / 24 = <u>3/4</u>
<u>5. In Ms. Ashley's class, are there more students that wear glasses or do not wear glasses?</u>
<u>There are 14 students with glasses and 7 without glasses.</u>
