To draw a double number line, we will label one side with the number of students and the other side with the percentage of students.
On the number of students side:
0----------------200
On the percentage side:
0----------------100%
Now we need to mark the point where 140 students fall on the number of students side:
0---------140-------200
To find the corresponding point on the percentage side, we need to calculate the percentage:
Percentage = (Number of students playing on a sports team / Total number of students) * 100
Percentage = (140 / 200) * 100
Percentage = 0.7 * 100 = 70%
So on the percentage side, the mark for 140 students will be:
0---------140-------200
0----------------70%
This double number line can be used to find the percentage of students who play on a sports team at Elmdale Middle School.
At Elmdale Middle School, 140 of the 200 students play on a sports team. (a) Draw a double number line that can be used to find the percentage of the students who play on a sports team
