I have a bar graph that shows the number of students by major in the College of Arts and Science.
Math shows 200 students
History shows 300 students
English shows 400 students
Science shows 150 students
Other shows 175 students
What percent of students in the college are history majors (to the nearest tenth of a percent)?
- I would take the total number of students divided by the history students number, right
Would it be 200+300+400+150+175= 1225
Then 1225 divided by 300=4.083
Then I would move the decimal over two places. Am I on the right track?
no, you are dividing the wrong way.
you have to divide 300 by 1225 ,not 1225/300 the way you have it
300/1225 = .24489
now you move your decimal 2 places to the right to get 24.5%
I see. I understand. I was wondering why I was getting such a weird number. Thank you!!
Well, I must say you're certainly on the right track, but your calculations went a bit astray there. Let me help you out with the math.
To find the percentage of students in the college who are history majors, you need to divide the number of history students by the total number of students and then multiply by 100 to convert it to a percentage.
The total number of students is 200 + 300 + 400 + 150 + 175 = 1225, just as you said.
The number of history students is 300.
To find the percentage, you'd divide 300 by 1225, which gives you approximately 0.2449.
Multiplying that by 100, we get 24.49%.
So, to the nearest tenth of a percent, approximately 24.5% of the students in the college are history majors.
Hope that clears things up!
You're on the right track, but you need to divide the number of history students by the total number of students to get the percentage. Here's the step-by-step calculation:
1. Find the total number of students in the college: 200 + 300 + 400 + 150 + 175 = 1225 students.
2. Divide the number of history students (300) by the total number of students (1225): 300 / 1225 = 0.2449 (rounded to four decimal places).
3. Convert the decimal to a percentage by multiplying it by 100: 0.2449 * 100 = 24.49%.
So, approximately 24.5% of the students in the College of Arts and Science are history majors (rounded to the nearest tenth of a percent).
You're on the right track, but there is a small correction needed.
To find the percentage of students who are history majors, you need to divide the number of history students by the total number of students and then multiply by 100.
In this case, the number of history students is 300 and the total number of students is 1225 (200 + 300 + 400 + 150 + 175).
So the calculation would be:
(300 / 1225) * 100 = 24.49
Now, rounding to the nearest tenth of a percent, the answer would be approximately 24.5%.
