    Answer:

    TOTAL NUMBER OF STUDENTS=72

    NUMBER OF STUDENTS WHO PARTICIPATED=7/12 × 72

    NUMBER OF STUDENTS WHO DID NOT PARTICIPATE=x

    NOW (7/12×72)+x = 72

    SO. 42+x = 72

    x= 72-42 = 30

    THEREFORE X = 30 WHICH IS NUMBER OF PARTICIPANTS WHO DID NOT PARTICIPATE IN RECYCLING ACTIVITIES
