A proportional relationship can be used to solve a mixture problem by comparing two related quantities. In this case, we can determine the proportion of students who choose band or choir in the incoming sixth grade class.
Let's say there are 100 students in the incoming sixth grade class. We need to find the proportion of students who choose band or choir.
Let's assume that 70% of the students choose band and 30% choose choir.
To find the number of students who choose band, we multiply 100 students by 70%:
Number of students choosing band = 100 x 0.70 = 70 students
To find the number of students who choose choir, we multiply 100 students by 30%:
Number of students choosing choir = 100 x 0.30 = 30 students
Therefore, based on the proportional relationship, 70 students choose band and 30 students choose choir in the incoming sixth grade class.
Use proportional relationships to solve this mixture problem. The incoming sixth grade class has a choice between band or choir
