Question

400 total kids. 200 high school, 200 college. Question: What percentage of the students are college kids that prefer history? 70 chose history, 60 chose math, 70 chose science.

Answer 1

Given:

Total number of students = 400

Number of high school students = 200

Number of college students = 200

NUmber of college students who chose history = 70

Number of college students who chose math =60

Number of college students who chose science = 70

To find the percentage of the students that are college kids that prefer history, apply the formula below:

`\text{ \% of college that prefers history = }\frac{Number\text{ of college who chose history}}{\text{Total number of students}}*(100)/(1)`

Thus, we have:

`\begin{gathered} \text{ \% of college that prefers history }=\text{ }(70)/(400)*(100)/(1) \\ \\ \text{ \% of college that prefers history }=0.175\text{ }*\text{ 100 = 17.5\%} \end{gathered}`

Therefore, the percentage of the students that are college kids that prefer history is 17.5 percent

ANSWER:

17.5%
