anonymous · Answer

% of students in the 6th grade = (6th grade students/total number of students) * 100%
                                            = (60/45+25+60+50+60+45) x 100%
                                            = (60/285) x 100%
                                            = 21.0526... = 21 ( to the nearest digit)
