Question

At KEY Middle School, there are 240 girls and 160 boys. What percent of all the students are girls?

Answer 1

girls + boys = 400
240/400 x 100/1
0.6 x 100 is 60
60%

Answer 2

Given;

Number of boys = 160

Number of girls = 240

Total number of students = 160 + 240 = 400

To find the percentage of all students that are girls, use the formula below:

`\begin{gathered} \text{ \% of girls = }\frac{Number\text{ of girls}}{Total\text{ number}}*(100)/(1) \\ \\ \text{ } \end{gathered}`

Therefore, we have:

`\begin{gathered} \text{ \% of girls = }(240)/(400)*(100)/(1) \\ \\ \text{ = }0.6\text{ }*\text{ 100 = 60\%} \end{gathered}`

The percent of all the students that are girls is 60 percent.

ANSWER:

60%
