    Answer:the number of sixth graders is 28

    Step-by-step explanation:

    Total number of students in the school band is 70. 40% are sixth graders. 20% are seventh graders and the rest are eighth graders. This means that the percentage of eighth graders is 100 - (40+20) = 100 - 60 = 40%

    This means that the number of sixth graders would be 40% of the total number of students in the school band. It becomes

    40/100 * 70 = 0.4*70 = 28
