Sixty percent of the sixth grade students at Jackson Middle School play a sport. If 114 sixth grade students play a sport, how many sixth grade students are there in the school? You are given the part, 114 students, and the percent, 60%. You need to find the whole. In other words, 60% of what number is 114? You can use bar diagrams, ratio tables, double number lines, and equivalent ratios to find the whole. Method 1 Use a bar diagram. Sixty is a multiple of 10 and 10 is a factor of 100. Draw a bar diagram with 10 equal-size sections of 10% each, because 10 x 10 = 100. Shade 6 sections to represent 60%. Label the shaded sections as 114 students, because 60% of the whole is 114. MA.6.AR.3.5 -114 students - Percent 0% 60% sul 100% Each section represents the same number of students. There are 6 shaded sections.
