Be Precise Of the number of sixth grade students at a middle school, 120 prefer online magazines over print magazines. Of the number of seventh grade students, 140 prefer online magazines. A student said that this means a greater percent of seventh grade students prefer online magazines than sixth grade students. Is the student correct? Choose the correct statement that uses precise mathematical language to explain. Multiple choice question. cross out A) no; A percent compares the part to the whole. In this case, the only known value is the part. To compare percents, the whole, the total number of sixth grade students and the total number of seventh grade students, must be known. cross out B) yes; A percent compares the part to the part. In this case, both parts are known. The number of sixth grade students who prefer online magazines, 120, can be compared to the number of seventh grade students who prefer online magazines, 140. So, a greater percent of seventh grade students prefer online magazines than sixth grade students. cross out C) no; A percent must always be less than 100. There are 120 sixth grade students who prefer online magazines and 140 seventh grade students who prefer online magazines, and both of these values are greater than 100. So, they cannot be compared as percents. cross out D) yes; A percent compares the part to the whole. In this case, the known values are 120, which is the part, and 140, which is the whole. Because 140 is greater than 120, a greater percent of seventh grade students prefer online magazines than sixth grade students. Need help with this question?
