There are 64 students in a middle school band. Five out of every eight are in the 7th grade.
Part A : What are the number of students in each section?
Part B: What are the number of students in the band who are in the 7th grade?
Part A: To find the number of students in each section, we can divide the total number of students (64) by the fraction of students in the 7th grade (5/8).
Number of students in each section = Total number of students / Fraction of students in the 7th grade
Number of students in each section = 64 / (5/8)
Number of students in each section = 64 * (8/5)
Number of students in each section = 102.4
Since it's not possible to have a fraction of a student, we need to round the number of students in each section down to the nearest whole number.
So, there are 102 students in each section.
Part B: To find the number of students in the band who are in the 7th grade, we can multiply the total number of students (64) by the fraction of students in the 7th grade (5/8).
Number of students in the 7th grade = Total number of students * Fraction of students in the 7th grade
Number of students in the 7th grade = 64 * (5/8)
Number of students in the 7th grade = 40
