Suppose 8 out of every 20 students are absent from school less than five days a year.pridict how many students would be absent from school less than 5 days a year out of 40,000 students.
8/20 = x/40,000
Cross multiply and solve for x.
To predict the number of students who would be absent from school less than 5 days a year out of a total of 40,000 students, we can use proportions.
Given that 8 out of every 20 students are absent, we can express this as the ratio: 8/20.
To find out the number of students absent out of 40,000, we set up the proportion:
(8/20) = (x/40,000)
To solve for 'x', we cross-multiply and solve for 'x':
8 * 40,000 = 20 * x
320,000 = 20x
Dividing both sides by 20:
x = 16,000
Therefore, we predict that approximately 16,000 students would be absent from school less than 5 days a year out of a total of 40,000 students.
To predict the number of students who would be absent from school less than 5 days a year out of 40,000 students, we need to use the information given: 8 out of every 20 students are absent less than 5 days a year.
First, we need to calculate the ratio of students who are absent less than 5 days a year. We can do this by dividing the number of students absent by the total number of students:
Absence ratio = Number of students absent / Total number of students
We know that 8 out of every 20 students are absent, so the absence ratio is:
Absence ratio = 8 / 20
Now, let's calculate the number of students who would be absent from school less than 5 days a year out of 40,000 students. We can do this by multiplying the absence ratio by the total number of students:
Number of students absent = Absence ratio * Total number of students
Number of students absent = (8 / 20) * 40,000
Now we can solve the equation:
Number of students absent = (0.4) * 40,000
Number of students absent = 16,000
Therefore, we predict that out of 40,000 students, approximately 16,000 students would be absent from school less than 5 days a year.
