    The percentage of left-handed 6th graders is 20%.

    Step-by-step explanation:

    To find this, start by finding the total number of lefties.

    19 girls + 11 boys = 30 students.

    Next find the total number of students

    90 girls + 60 boys = 150 students

    Now divide the lefties by the total number.

    30/150 = 20%
