B) The same number of students from each grade whose names are randomly selected from a hat
E) 50 sixth graders, 67 seventh graders, and 62 eighth graders
Step-by-step explanation:
B) The reason B is correct is because if all grades get to pick, with the same amount of people from each grade, it would be fair for most, if not all, students.
E) E is correct because of percentages. Let me show you.
6th Grade | 150 Total Students | 50 Students Vote | 33.3% of 150 is 49.95. Round to the nearest whole to get 50.
7th Grade | 200 Total Students | 67 Students Vote | 33.3% of 200 is 66.6. Round to the nearest whole to get 67
8th Grade | 187 Total Students | 62 Students Vote | 33.3% of 187 is 62.271. Round to the nearest whole to get 62.
(C)
Step-by-step explanation:
A. The given fractions are:
Upon solving , we get
which is not possible, therefore this proportion does not show equivalence.
B.The given fractions are:
Upon solving , we get
which is not possible, therefore this proportion does not show equivalence.
C. The given fractions are:
Upon solving , we get
which satisfies the equivalence of two fractions, thus this is correct option.
D.The given fractions are:
which is not possible, therefore this proportion does not show equivalence.
