“What is the student enrollment (in the total number of students)?”
To find the ratio of the number of girls in the band to the total number of students, first calculate the total number of students: 17 boys + 12 girls = 29 students. The ratio of girls to the total number of students is 12 girls to 29 students, which can be expressed as 12:29.
If the total number of people is T, then there are 19*T/20 students.
To find the percentage of students absent, divide the number of absent students by the total number of students and then multiply by 100. For example, if 10 students are absent out of a total of 50 students, the percentage absent would be (10/50) * 100 = 20%.

Let's denote the number of students in XYZ national high school as "x". According to the information given, the number of students in ABC national high school is 3x - 40. The total number of students in both schools would be x + 3x - 40, which simplifies to 4x - 40.
x*0.15=60 x=60/0.15 x = 400 400 books
The number of newspapers is calculated by dividing the total number of newspapers read by students by the number of times each newspaper is read. In this case, with 300 students reading 5 newspapers each, the total number of newspapers read is 300 students * 5 newspapers = 1500 newspapers. Dividing this by the number of students who read each newspaper (60 students) gives 1500 newspapers / 60 students = 25 newspapers in total.

You don't tell the total number of students. To get a percentage you need to provide the total.
