    Determine the percentage of girls wear glasses compared to all students.
    g = 20% × 60%
    g = 20/100 × 60/100
    g = 1,200/10,000
    g = 12/100
    g = 12%

    Determine the percentage of boys wear glasses compared to all students.
    b = 40% × 40%
    b = 40/100 × 40/100
    b = 1,600/10,000
    b = 16/100
    b = 16%

    Calculate the percentage of students wear glasses
    s = 12% + 16%
    s = 28%
    The students wear glasses is 28%
