What percentage of the students who chose biking were seventh graders?
A. 30%
B. 37.5%
C. 40%
D. none of these
To calculate the percentage of the students who chose biking that were seventh graders, we need to first find the total number of students who chose biking and the number of seventh graders who chose biking.
Total number of students who chose biking: 5+3 = 8
Number of seventh graders who chose biking: 3
To find the percentage, we can use the formula:
(Seventh graders who chose biking / Total number of students who chose biking) x 100
(3/8) x 100 = 37.5%
Therefore, the answer is (B) 37.5%.
Oh, percentages! I love those little math buggers. Let's break it down, shall we?
In total, we have 5 sixth-graders and 3 seventh-graders who chose biking. So out of a total of 8 students who chose biking, the seventh-graders make up 3 out of 8.
To find the percentage, we divide the number of seventh-graders (3) by the total number of students who chose biking (8) and multiply by 100. So, (3/8) * 100 = 37.5%.
Therefore, the answer is B. 37.5%. Those seventh-graders sure know how to ride those bikes!
To find the percentage of seventh graders who chose biking, we need to compare the number of seventh graders who chose biking to the total number of students who chose biking.
From the given table, we can see that the number of seventh graders who chose biking is 3.
To find the total number of students who chose biking, we add the number of sixth graders and seventh graders who chose biking: 5 + 3 = 8.
Now, we can calculate the percentage of seventh graders who chose biking by dividing the number of seventh graders who chose biking by the total number of students who chose biking, and then multiplying by 100.
(3 / 8) * 100 = 37.5%
Therefore, the correct answer is B. 37.5%.
To find the percentage of seventh graders who chose biking, we need to divide the number of seventh graders who chose biking by the total number of students who chose biking.
From the table, we can see that 3 seventh graders chose biking.
To find the total number of students who chose biking, we add the number of sixth graders and seventh graders who chose biking: 5 + 3 = 8.
To calculate the percentage, we divide the number of seventh graders who chose biking (3) by the total number of students who chose biking (8) and then multiply by 100: (3/8) x 100 = 37.5%.
Therefore, the correct answer is B. 37.5%.
