Fifteen percent of the respondents rated Excellent; 60% rated Very Satisfactory; 80% of the remaining respondents rated Satisfactory and the rest rated Needs Improvement. If 120 parents answered the survey, how many of them rated Needs Improvement? Let's be accurate as possible. <hau> Wata makaranta ta gudanar da bincike ga iyaye game da kwarewar karatun kan layi na yaransu.
