Answer: The  number of students not in the marching band is 346.5  Step-by-step explanation:Given as :The total number of children that attend a high school = 450The percentage of students in the marching band  = 23 %Let The number of students not in the marching band = xNow ,∵ The percentage of students in the marching band  = 23 %∴ The percentage of students not in the marching band  = 100 % - 23 % = 77 %So, The number of students not in the marching band = 77 % of the total number of students in the schoolI.e  The number of students not in the marching band = 77 % × 450Or ,  The number of students not in the marching band = [tex]\frac{77}{100}[/tex] × 450∴ The number of students not in the marching band = 346.5 And The number of students in the marching band = 450 - 346.5 = 103.5Hence The  number of students not in the marching band is 346.5  Answer
