  1. Step-by-step explanation:

    In class a total student who are absent

    • 25-17=8
    • percentage= 8/25*100=32%

    In class b total student who are absent

    • 20-14=6
    • percentage= 6/20*100=30%

    In class c total student who are absent

    • 24-18=6
    • percentage= 6/24*100=25%

    a)In class A = 32%

    In class b = 30%

    In class c = 25%

    b)Class A had the worst percentage record for absence=32%
