the ratio of juniors to seniors is 9 to 8, if there are 51 juniors and seniors total, which percent of students are seniors?
how do i figure this out?!
We don't even need the 51
Can you see how 9/17 of the students are juniors and 8/17 are seniors?
8/17 = .470588
so 47.1% are seniors
To figure out the percentage of seniors, you need to find out the total number of seniors and then divide it by the total number of students (juniors and seniors combined), and then multiply by 100 to obtain the percentage.
To solve this problem, we first need to determine the number of seniors. Given that the ratio of juniors to seniors is 9 to 8, and we know there are 51 juniors and seniors total, we can set up the equation:
9x + 8x = 51
17x = 51
x = 51 / 17
x = 3
So, there are 8x3 = 24 seniors.
Next, to find the percentage of seniors, we divide the number of seniors by the total number of students (juniors + seniors), and then multiply by 100:
(24 / (51)) * 100 = 47.06%
Therefore, approximately 47.06% of the students are seniors.
